I received my projector (Optoma HD72) and am using it with my 970/7125 combo. Right off the lip sync was not sync'd. I have found that the maximum lip sync delay of 200ms is not enough.
I either need to speed up the video feed or slow down the audio.
The video is from an Oppo DVD player out DVI to DVI in on the 970 and from DVI out on the 970 through a DVI to HDMI converter to HDMI in on the HD72.
Any ideas?
