Every time my BDV-E190 Blu-ray player does a firmware update it seems that another app stops working!

I've had the BBC iPlayer 'SSL Alarm Display' error for months without a fix:

The YouTube app stopped working at the same time, but that seems to have been fixed now, but since the most recent update the Demand 5 app won't play any videos and gives the following error message:

"Whoops! The programme you are trying to watch isn't currently available. Please try again later."

(SONYD5-530)

It does this for every programme I've tried, yet the same programmes are available on the PC browser version of Demand 5.

I know that I can do a factory reset and that will probably fix the problems but I don't want to do that because I'll have to re-configure all my audio and network settings and the same thing will happen again in the future. Why can't these updates be tested more thoroughly before they get rolled out?

Current software version: M12.R.0497
