I find that iPlayer is almost unusable from between 6pm-10pm when using our Bravia TV ( due to constant buffering interruptions), other services like YouTube and LoveFilm seem fine on the TV. Also, iPlayer on a laptop (same connection) works just fine.

I thought that the TV would connect to iPlayer in just the same way as the laptop, is that not right? Any clues on how I can sort this out, it's very irritating.

We're using BT Infinity 2 (76MB down/20MB up), it's a wired 100MB ethernet connection to TV. A speed test using (speedtest.net) at the same time as problems occur is showing 46down/9up.
