 <reposted from my thread on the MythUsers list>

 long time Myth user, did the 0.22 upgrade this weekend using ATRPMS repo..
 everything went smoothly after a little google-foo for QT4.4 on Centos..
 Backend (Centos54-64-bit) flawless upgrade, zero issues since. Frontend
 (Mythdora 10.21) little more pain, but got it upgraded as well.

 Backend: Tyan S28xx series, 2xOpteron 285, 8G ram, 3ware 9500 w/lotsa
 drives, dual GIG-e to switch, 2xHDHR OTA
 Frontend: MSI AM2, 6400BE at 3.2ghz, 9600GT, HDMI to Sony TV

 I've been using VDPAU with mplayer SVN + NVIDIA 180 drivers for a few
 weeks, with zero issues. Picture is beautiful, smooth, crisp, and it's a
 little spooky to see 10% CPU with 1080p playback active.

 However, VDPAU in myth has me less impressed today. Over the weekend
 watched probably 10+ hours of mixed HD playback, almost all recorded
 from ATSC-air from HDHR's.  Almost all of it  had what I can best
 describe as Horizontal fragments / bands / sparkles that would
 randomly appear, almost like noise throughout playback. They would
 stay on the screen less than 1 second each, but at times you could
 have lots of them on the screen.

 If I go back into "playback profiles" and set back to
 CPU/CPU+/anything non VPDAU, same source, no noise. No change in the
 "deinterlace profiles" under VDPAU changes the behavior.

 Other things I tried:

 - 2 different video cards - 8500GT and 9600GT.
 - 3 different driver revisions, 180, 185, and 190
 - multiple different on-air sources, 480p, 720p, and 1080i
 - liveTV seems to be worse than recorded, but not by much..

 Again, non-VDPAU = no noise/artifacts

 Playback of non-HDHR sources like H.264, VOB, etc,in mplayer produces ZERO
 artifacting.

 It doesn't appear to affect stability, but it's downright irritating..and
 obviously a symptom of something broken.

 the mythfrontend.log isn't giving up any help either, but perhaps I
 don't have debug high enough.. I'm getting some NVP: prebuffering, and
 WriteAudio: buffer underrun, but only every couple minutes.. nothing to
 correlate to the constant artifacts.

 I'm attaching both the xorg.conf and "-v playback" logs.
