Over xmas my 880 has failed to record after I set the timer.
It worked ok for the first couple of times then it just doesn't record after I have set the timer and put it into standby mode.
After setting the timer over and over again and it failing to record I ended up pulling the power cable out, starting it up again and then setting the timer, putting on standby and it worked again!
It also stoped me seeing sky which normally works ok and could be viewed through ext2. As soon as I rebooted the system, sky reappeared!
Also I set the recorder to record 1.5hrs via the record button ie pressed 3 times & the count down showed 1.5hrs. Come back to watch the programme, only 1hr had been recorded.
I have phoned the philips helpline, they said it might be a faultly unit, sent it back to the retailer.
