Here's what happened:[LIST][*]Was watching Child Of Our Time last night on iPlayer higher quality - all fine.[*]Spring Watch started recording whilst I was doing that.[*]At end of Child Of Our Time I tried to watch episode 2 and it just said loading for a few mins.[*]I was able to exit back to normal TV.[*]Went back into iPlayer and tried to play it again.[*]This time the box froze, nothing would respond.[*]It was gone 9PM and Spring Watch was still recording (didn't stop on schedule I could hear the HD when I put my head close to the box).[*]After cutting the power and rebooting, all worked OK. The Spring Watch recoding showed as failed.[/LIST]Anyone else had such a scenario?

I've not used iPlayer much so far...!

Yes, we've had those exact symptoms on our box. I think it's when our internet connection stops or slows down too much. Then the i-player sometimes freezes, and the only way to get it back is to unplug it. And like you say, as you would expect that stops any recordings that were running.
I suppose that's why its still "Beta".
