iPlayer on the TiVo box continues to be unwatchable - everything else works fine including catch up. I can stream iPlayer from my iPad without buffering on wifi but hard wired Tivi box is useless - this problem has been around for ages - catch up for other channels works well, if they can't sort iPlayer can't we have the BBC programmes delivered in the same way?
I'm having exactly the same issue with IPlayer constantly buffering or loosing connection completely; even when you reboot system it can either work for a short while or still be exactly the same issue - it's an absolute pain. When I watch IPlayer over wifi from iPhone or iPad it works perfectly. It's definitely an issue with the TIVo box
