I've read a few threads on here about freeze ups and I guess that would certainly explain it (though i've not noticed any yet during normal operation. that would have to mean they also occur when the machine is in standby mode?).
We went fully digital down here a couple of months ago and the unit has only ever experienced the current, more powerful digital signal.
Pretty annoying to be 0 for 2 so far. Will give it a couple more chances, but if the problem persists it will have to go back. Annoying - thought i'd eradicated the need for the annoying heap of random and incorrectly labelled DVD+Rs
