I'm a newbie to Dish after 20 years of C-Band. I switched because of the loss of more and more channels available to my 4DTV. Dish Net seems to be OK, except for a varying audio/video sync problem. The audio lags the video on most channels, some more than others. I don't see this mentioned much on this forum, however. The CSR says a fix was coming last month. So far, no fix. Is it a receiver problem? If I'd known about this, I would not have signed up. Also, the "caller ID" feature does not work. I've heard it is only available thru the RF output. We use the S video out. CSR didn't know, but said "it might be a bad modem". Phone line is OK, and feature is enabled. Caller ID works on phones in the house. Any ideas?
