I just did an upgrade from Dish which included a new HD receiver and a newer HD DVR in my home theater room. I have the HD DVR hooked to my 970 via optical cable and stereo cables. I am having the following issues with the newer model HD DVR.

When I change channels on the DVR there is static from the speakers until the channel locks in. Once the channel locks there is no static present. Also when I stop a recorded DVR event there is static present until I resume play.

I checked a few things and one was setting the 970 to analog input from the DVR. With this setting there is no static. Then I checked the optical connection which looks OK.

I did not have this problem with the older HD DVR.

Does anybody have any recommendations on what could be causing this probem?
