I've just tried to watch subtitles on the Strictly Come Dancing results show from 15th October. They are badly out of sync, mostly 10 seconds, but sometimes over 30 seconds behind. I have a BT DTR-T2100 box, but my ISP is TalkTalk. Is the problem with iplayer, or the box and its current software? I had to replace my previous DTR-t2100 due to water being spilt on it, so this box has never been used until a few days ago.
