Another show didn't record. This after doing a complete Clear and delete. Fortunately I simultaneously recorded it on unit#2. Last weekend only 1:43 of 4:00 starting at the same time on the same channel recorded. Now I could buy a couple of new power supplies but it is quicker and cheaper to just put the old 40GB HDs with 6.2 on them back in. But I do not ever want the software to be upgraded again! Absolutely sure 6.3 loaded via telco?
