Thanks for the detail. I never saw a problem with stuttering during
playback of the sample tst.ts file provided by pchdtv.org. I also
tried a few other HDTV demo clips I have and didn't see a stutter
problem with them either. The problem is mainly the over all quality
of the image in the tst.ts test file offered on the pchdtv.com
download page. My own demo clips from other sources look just fine
and my concern is that the test clip provided by pchdtv.com shows how
poor the video recorded from the HD3000 is. I hope that's not the
case! :)
The card in the P4 (the current MythTV box) is a lowly ATI 7500 PCI
running at 1280x720 and hooked via DVI to my Panasonic HD L500U
projector. When I get the HD3000 card (I haven't ordered yet, I'm
still concerned about image quality of the sample clip as described
above) I'll also be updating the ATI video card to something better.
