Same kind of thing in Sacramento. I don't have HD, but audio and video trouble during CSI tonight. It has happen in the past also. I kind of half heartely thought it was Dish messing with the mpeg2 signal to get me to upgrade.
Another option is a Slingbox. If you have a wireless network, it works rather well. I have a slow DSL, so the PQ over the net is rather poor. It will do HD, but I only have SD, so not sure how it woud look.
Is there some one close enough who has dish also? Try changeing the chanel your remote transmitts on. I had that problem before, all of a sudden I would be watching a spanish channel. I don't speek spanish.
