Tried to use BBC iplayer via my TiVo box at 8.30 this evening and had to give up as it kept buffering every 2 or 3 seconds. In the end had to watch the programme on my iPad. I even switched the TiVo box off to reboot. Exactly the same. I'm extremely frustrated.
So are many people I'm afraid. The BBC iplayer app is poor to say the least. It's produced by the BBC to run on TiVo so until the BBC and VM get their heads together her it won't improve. I've reported to both VM and the BBC. The BBC said they were unaware of any problems, asked me for details and supplied me with an unusable email address so my emails bounced back!
