I just got the HR20 installed, and it seems to working as advertised but the one big issue I'm having is bad audio syncing issues. Some of the channels are just sligitly off, while others, such as my local HD FoX channel is VERY noticible to the point of annoyance. I am usind HDMI for the picture but using toslink (optical) cable for sound as my receiver doesn't have HDMI. I tried going to list and back out as suggested in the Tips and Tricks document but that didn't seem to do the trick. Also tried swapping out optiical cable with another one, didn't matter. So what could cause this. Would I be better off foregoing the HDMI cable and using componant? How much picture quality would I lose?
