Got home today and my box would not come on again

Only indication on the box front was "REC" on the display.
Pulled out the mains adapter lead and plugged it backing in.
Box said "Starting" then went to sleep.
Powered up and okay again but the last recording said "Ice Cold In Alex" Part Recorded 150/155 but it actually finished over 30 mins ago.
Perhaps the new accurate start data on the channel 4 family of channels does have a problem?
Automan.
