A month or so ago, I got a new Dish HD DVR. I'm feeding my Panasonic AX100u 720p projector from the Dish DVR with HDMI. I also have a VGA feed from an HTPC to my projector as well; my HTPC runs BeyondTV.
Yesterday, I noticed "Blast from the Past" was on local channel 20 (I'm in Houston). For some reason, 20 isn't in HD on Dish...anyway, I pulled it up. And the quality was HORRIBLE - very very dark and very very pixelated. Really looked nasty.
So, just for the heck of it, I pulled it up in BeyondTV...and it was be-yoo-tiful. I mean, it wasn't HD quality, but it was night and day difference between BeyondTV through VGA and Dish DVR through HDMI.
Anybody got any ideas on that? I'm guessing Dish's de-interlacer/de-scaler/whatever isn't as good as BeyondTV's, or else they're not using the "native" digitized version of channel 20 and are doing their own analog-to-digital capture before sending it up to the satellite, but who knows...all I know is that I certainly wasn't expecting that.
I'm tempted to try a different feed to the projector from the Dish DVR - maybe component, see if it's any different.
