WE just got an update from Dish about this issue..There is a software issue wiht 622's right now. The HDMI cable will not deliver aud or vid from the HD channels..Dish is working on this..When my Dish 622 was installed last week I had bought a HDMI cable in advance. When the installer was hooking up the receiver I told him I had the HDMI cable and he said he did not need it, he had cables. I did not realise until after he left that he connected the 622 to the TV via an S video and componant cables. I contacted Dish tech and they said the HDMI cables should have been used and that I could disconnect the S video and componant cable and hook up th HDMI cable. I did and no sound or video. I called Dish tech back and he reset the receiver, but still does not work. His only thought was that it was a defective HDMI cable or the the wrong settings on my Sonny HD TV. The cable is new. What setting on the TV would effect this.
Also, on my local channels through Dish I notice a lot of shows out of sync with the voice.

HD Audio/Video
If you encounter audio or video issues in the field that are specific to certain channels, but not impacting all of the programming, please email (dedacted)so that we can research issues that may be related to these channels. In the email please include the specific channels and receivers that the issues occur on (i.e. Model 622 has intermittent audio loss on all HD channels). Technicians should not RA receivers exhibiting intermittent audio or video issues if they are happening only on specific channels.
Hope this helps..
