More then a few times I have set Autotune to record a program and end up with a blank screen.  The D12 doesn't turn on.  One time it was in the middle of a recording and I noticed the blue light on the D12 wasn't lit.  So I turned it on manually.  The D12 indicated an autotune was in progress and would I like to cancel it?  Sometimes it works fine.  But I can't trust it.  Anyone else have this happen?  Also when I turn the D12 off, the blue light flashes twice before turning off.  ????
