I see the stuttering on a lot of HD Channels including OTA, but not very often. However, on ESPNHD it happens quite frequently. My HR10-250 was about a year old and I've been wanting another one so I bought a new one and it does the same thing. Guess we should all be reporting this to DTV and see what they say.........but based on past experience with reporting probs to them it's probably not worth the frustration of trying to convince them it's not a problem with my dish or box. I'm guessing they know about the problem but don't have a fix and are working on one?
