I found a problem last night with my SKY HD box that am curious if its me, my box or a common problem. Whilst recording Pirates of the Carribbean I tried to start watching it whilst it was still recording and and juddered like it was constantly losing signal. I left it last night expecting to have to delete it today and found it played great. So tonight I was sitting here watching the movie and half way through it my recorder starts recording Billy Elliot in HD and again the play back goes judder-city. So the common factor here is that I cant watch an HD recording whilst recording anything HD. In fact I tested playing back a standard SKY recording and found it fine... So... Just me? Or is this common? Appreciate any feedback.
