Hard to say.
TalkTalk basically ignored the entire discussion and their customers ended-up squabbling with some people totally convinced there was something fishy and others calling them paranoid (and worse).
The basic idea was that TalkTalk were "doing something" that "broke" iplayer. The main suggestions were that it stemmed from phorm-style interception and redirects or else content filtering from TT playing "nanny" with customer's content.
The main impetus for the idea stemmed from the fact that A LOT of sony users couldn't access iplayer for a very long time or had repeatedly problems. That started being discussed on various forums including TalkTalk's - and someone joined the dots and came-up with a theory.
One of the most cited arguments against the TT theory was that BT customers were also affected but there was little clarity in those threads - hence asking about bundled/unbundled.
The main reason for asking about it here was to try to deal with that before it became another conspiracy theory. If there's no commonality involved in terms of the ISP, we can reasonably dismiss that as a possible cause (plus, knowing that BT and TT customers are affected removed other local elements such as a particular brand/re-branded router - BT hubs and TT D-link tat are very different animals).
There is one "nagging question" and that's whether any ISP that DON'T have TV-streaming services are affected - just in case it's linked to QoS (or any similar system being used to ensure a "smooth" connection for "prioritised" data). I can't check that where I live - around here it's BT or TT, that's it.
To be honest, I'm just trying to pass the time until sony admit that they cocked something up with the software update (note - NOT the later firmware update that did precisely nothing).
