I'm not lying or in denial, my 630 just works well. I've had some resets, and a couple missed recordings, but nothing to the extent of what has been reported here.
I always find the number of posts with things like "my wife is pissed" "my wife is tired of this" absolutely hilarious. Are there really that many angry wives? (Don't answer that)
Peano raises a good point. I've gone on a mission to make my 630 crash several times by repeated FF/RW, skip ahead/back, enter/exit guide, and it always performs.
QC very well may be the problem. Recall that there were rumors that Shaw and Moto were having difficulties coming to terms with QC targets. Perhaps that was true?
