One more question. If I connect the video from a cable box directly to an HDTV with a hdmi cable and the sound to the 970/990 through a digital cable from the cable box. Could I still use lip sync function in the 970/990?

I guess I am trying to figure out if I could take care of a lip sync problem with the 970/990 without an HDMI input. My brother has the same TV I am considering buying and reports have occassional problems with audio being out of sync with the video.

Thanks.
