I have an hr21-700, and I've been noticing the last couple of months that every show that is recorded gets the first minute chopped off and records too long(actually it is like there is almost a two minute difference, I've not actually checked to be sure.) It is as if the clock on the dvr is off by a minute or two. Now I know that I can always tell my shows to record a minute or two early, but much like everyone else, my dvr is loaded up with crap to record, and I dont want it to miss recording one show because another one is scheduled to start 1 minute early. The obvious fix to me is to reset the clock. So I called directv and was told that all I could do was a. record ALL my shows 2 minutes early or b. reset the machine. I just reset the machine and dont know if that fixed it yet or not, but I'm sceptical. The person I talked to seemed not very knowledgable at all, and I've never called and had a problem with the dvr fixed before. Was wondering if anyone else has noticed this or is it just my box? She told me that the satallites are what determines the time on the dvr. Is this true and if so wouldnt everyone be having this issue? I was also told that some networks start shows earlier than others, but this is EVERY SINGLE CHANNEL. Any suggestions?
