Amazon Video - Juddering Issues

faheemrazzaq — Mon, 27 Feb 2017 23:46:35 GMT

I have upgraded my 55xd9305 yesterday and it proved to be a bad move. Since then a lot of judder specially on 4K stuff from Amazon and YouTube. It settles if left alone for couple of minutes. Clicking a buttong on remote such as volume or action will again introduce judder. I also noticed that while watching some 4K HDR on Amazon last night, the sound was out of sync with video as well. I hope a fix comes soon.

This is not the same kind of judder that this thread is talking about. You should make a seperate thread. I can confirm I have seen this issue, particulary in Amazon prime.

Hi Both

I have separated these two posts from the Sky juddering thread as this is a different issue. I too can also confirm juddering in the following instances:

At the start of playback of video content - lasts a minute or two
At volume change - up or down
When bringing up playback controls and information

Cheers

Yes I can confrim the same issue. For Amazon Prime only (no issues with Sky Q) At start judders for a 0-15 seconds, and when volume changing judders for 0-5 seconds for every press of the button. But after 5 seconds all seems OK and is settles down. Weird.

Hi MarkF42.

I have had the same thing since I bought the TV and initiated my Amazon Prime subscription again. The sad thing is that if I watch Amazon through my BD Home Cinema on the TV I get no issues at all! It's only if I try to watch directly from the TV app that the stuttering playback happens. I don't even think it is just a 4k issues as it seems to happen no matter what I try to watch on Amazon. Can't comment on Netflix cos I cancelled that to resubscribe to Amazon Prime but when I did have netflix it played without issue!

Makes you wonder how it can be sorted when both the TV and the BD Home cinema are LAN hardwired to the same router.

Having said that, it is now the least of the TV issues! Since the recent Android software upgrade the TV poweres down and restarts on a regular basis.

I understand from previous replies on the forum that SONY cannot be held responsible for third party software issues on their SMART TV's but I think that's a cop out by a Company that should know better!

I used to notice the same with my 49XD8099 (from late 2016, so "ATV2" with MT5891). Then after the March firmware update for these tvs I thought the issue disappeared. But last night I watched a movie again in Amazon and changing volume it was a mess.

So I checked with "top" from the Termux app what was the CPU usage and indeed, being idle, the CPU was always 20-40% busy doing I don't know what. Other times I could see system processes from Sony (like DLNA or dtt, when I don't even use the digital terrestrial television) eating the CPU. This morning I checked the CPU usage again and it was quite idle (95% or so). So I tested an Amazon video and although the volume bar took ages to show, I didn't get any real major stuttering.

Any other video service (Netflix, Italian TIMvision, YouTube, Plex, etc) I use doesn't cause any of this issue any more. But they did before the last firmware update.

I don't know. It seems to me it's a mixed issue of the Amazon video app being far from optimised and some processes in Android TV getting stuck and thus eating most precious resources.

An intersting reply that goes some way to shed a little light on what appears to be a regular user issue.

I still maintain that Sony should address this issue directly and sort it out with a software update to rectify this and other matters rather than (as it seems to me) to be investigated and tested by owners. All I really wanted is a reliable and trustworthy modern TV! With the issues that I have had with this one since I bought it all that it means is that for my next TV it will NOT be a SONY. The frightening thing is that the Amazon service works perfectly on my SONY BD Home Cinema system. If it works on that, then why does it struggle on the TV??

I can give you the sarcastic (and sadly true) answer to this: because your BD Home Cinema doesn't run a memory hog OS which is plagued by the fragmentation, in this case with a Linux kernel and the source code of some OS parts made for a cheap SoC with very weak CPU cores, produced and maintained by a company (Mediatek) that isn't actually famous for the quality of their SW.

Also, to keep being honest, I am not a fan of the Amazon video app. It's slow even in the PS4. But at least it doesn't stutter. And with the PS4 controller it's less neurotic to use.

As I keep saying they should all learn from Plex and/or Netflix about how to make a great video streaming app. YouTube/Google included. I am not a fan of the YouTube video player either. But at least that one is fast.

Very true! Nothing premium about Sony TV with respect to application processor and software.

The Netflix experience indeed is great. And you find it on the app store which means that it respects the open app believe that we got so much used to on mobile platforms. Amazon is only on select devices/platforms, so those that pay the fee...

The only good thing about Amazon for end users is that it is quite cheap which is pretty much what it is worth though.

Yeah, the cheap part is what made me finally subscribing for good to Amazon Prime. I received the SMS for the 19.99€ payment yesterday, and it feels unnatural that I won't have to pay again for another year. Also considering that Amazon is my main online shop, so I will also benefit from the free 1 day deliveries. And the Video Prime content isn't bad at all. Hopefully they will enlarge the UHD catalogue, though.

Still, the app is bad. Sometime I start some videos and they play in German. The subtitles get turned off or change to another language as well. So do the font settings. And I did set all of them in the web. Move forward/backward is a huge pain with a remote. It drives me mad.

It just goes from bad to worse!

I wanted to buy a 4k Bluray player and have had such a poor relationship with Sony devices over the last 3 or 4 years I decided to opt for a Panasonic.

It set up without fuss or bother works from the Sony TV control!

The Amazon Prime service works without issue!

Once again;

if the Amazon service works with my Sony BD Home cinema, works with my Roku (everywhere throughout my home) and works perfectly with the new Panasonic 4K player THEN WHAT IS THE PROBLEM WITH IT NOT WORKING AS WELL WITH THE SONY TV????????

All are linked to the same broadband service via the same router either by wired or wireless.

COME ON SONY. SPILL THE BEANS. YOU ARE LETTING FAITHFULL AND LOYAL BUYERS DOWN BY PROVIDING UNPROVEN AND SHABBY EQUIPMENT ON THE LOOSE AND THEN HIDING AWAY FROM YOUR RESPONSIBILITIES WHEN SOMETHING IS OBVIOUSLY WRONG! FOR SHAME SONY.

I've encountered the same juddering issues on my 55XD9305, especially since the latest Android update. After reading these forums i tried a couple of the posted suggestions:-

1 - Complete Factory Reset of TV

2 - Amend permissions for 'storage' on Amazon Prime App.

Lo and behold all my juddering issues have disappeared - Amazon, Netflix, Youtube, Google - all play fine now with no juddering or brief pauses when using volume control etc.

Don't know if it's a combination of both or just one of them but it seems to have done the trick.

Happy Days!

Many thanks for the insight. I'll give it a whirl and see what happens.

Just to add a bit of news, I've just bought a Panasonic 4K Blu Ray "smart" player and the Amazon app works perfectly on that!

Makes you wonder eh???

Re: Amazon Video - Juddering Issues

allencresswell — Wed, 17 May 2017 13:22:46 GMT

hi,

thought I had better try this one and give it all time to settle down before reporting back the findings.

I have factory reset the TV and amended the storage permissions on the app and lo and behold..........................

no change!

Still judders and jerks and makes it impossible to watch directly from the TV app.

On the upside, it still works perfectly on the app on the Bluray Home cinema and indeed on the Panasonic 4k Blu Ray.

Makes you wonder what we used to do in the days before "Smart TV's".

Just an update. After upgrading to Android 7.0 the situation.. seems even worse! I tried a couple of UHD videos and at the beginning it was lagging, stutteiring like never before. Forget about changing volume or going into display settings.

One positive note, but I don't know if it will be a general rule or if it was a good day for the netwrok, it took less time going Ultra HD. Only few seconds.

This onlt started after the Marchmellow update. Strangely pausing it immediately it start for 30 seconds resolves.

Just to note that this issue doesn't happen with Netflix, even in 4K. It also settles after about 2-3 minutes of playback. Factory reset had no effect. I have a super-fast fibre connection, and the TV is connected via wireless to an Airport Extreme a few feet away.

For me, the juddering issue improved quite a bit lately. Apparently Amazon did some updates on the servers...

I've had this problem now since around May on my KD-55X8509C. I logged in last night to try again, expecting a fix after such a long time and it's still there!

Amazon plays fine on my xbox one, but stutters at random intervals via the Sony app. No other apps seem affected, it's purely the Amazon app.

Did anyone find a fix?
