I have 5 HD DVRs connected to SWM. I have a HR20 that looses video from time to time. I have rulled out cabling. Thinking it must be the DVR. Talked to DTV and they would look at it for about $50 or I could sign up for a maintenance contract. What do most users do? Keep buying new boxes, use the one time tech fee or sign up for the maintenance contract? My bill is over $100 per month. I just hate giving them more money. Thanks, Gary
