Using my "savings" from buying through DocDVD, I purchased the Direc TV HD Tivo and activated it on Sunday. We recorded Deadwood on Direc TV and Time Warner SA 8300HD, and CSI Miami on DirecTV and OTA. My observations: 1) couldn't see any significant difference between either source on "Deadwood". I thought TW was minutely better and wife thought Direc TV was minutely better. 2) OTA was definitely better than Direc TV for CSI. Conclusion: TW's compression is about equal to that of Direc TV. I have the SA 8300HD set up to pass through the native resolution, and have left the HR10-250 set at 1080i. SD on the Q006 is clearly better to my eye from the Direc TV Tivo box at 1080i than from the SA 8300HD at 480i. In fact, it's the best SD I've seen, period. It is better than that from my older Sony SAT T 60 Direc TV Tivo sending SD to the Q006 via the composite connection, my previous best. Conclusion: The HR10-250 has a pretty good scaler and the Q006 really likes it's output. Both source devices are sending the signal directly to the Q006 via HDMI on inputs 6 and 7. When we watch ABC HD, I'll switch between 720p and 1080i output from the HR10-250 to see if there is any difference, but I haven't gotten around to it yet. The Tivo unit's user interface is so much better than that of the SA 8300HD that we are dropping the TW HBO service. The only reason we don't drop TW entirely is it's the only place for my wife's "Tennis Channel".
