[mythtv-users] 0.21 HD playback problems

I am bringing up a brand new Fedora 8 system using ATrpms and Myth 0.21
release. It's the same hardware that ran well under Fedora Core 5 and
MythTV SVN source. SD works fine, but attempting to play an HD recording
hangs. I'm using the identical xorg.conf file that worked under the old
system. If I run nvidia-xconfig on this, the only thing that changes is
the comments. I have the XvMCConfig file set up correctly and the
necessary nvidia-graphics drivers and libraries are installed.

>From the log snippet below, the problem appears to have something to do
with deinterlacing, which I had turned off on the old system. The
problem is, I can't figure out how to do that under 0.21. I thought I
was hallucinating when I went through all the setup options again and
again without finding this, but then I went back and looked in the
"Hacking MythTV" book, and it mentions this as being under TV Settings
-> Playback -> General, but it's not there. This part of the setup
screen appears to have been completely reorganized under 0.21. So where
do I set the deinterlacing algorithm, or turn off deinterlacing? Is that
actually my problem?

Thanks,
