For the record, mine is the exact same way. I'm NTSC using the
640x480 modeline, but I'm following this thread intensely hoping
you'll find a good solution.
It's nice to know I'm not the only one. Unfortunately I haven't had much
progress. I recently tried swapping the FX5200 for
the 6800GT I have in my desktop computer, but the TV-out on that one
behaved exactly like the FX5200 in every directly observable way.
I still can't get it to have proper 25Hz refresh.
I did however find out why only the bobdeint filter results in a really
smooth looking video. Despite my modeline which gives me perfect mapping
between framebuffer lines and tv-out lines, I still get blending between
the fields. Setting the environment variable NO_XV=1 revealed that
XV is to blame. I got perfect "field separation" after that. I'm
guessing the video overlay window is scaled somewhat. Luckilly I'm able to
photograph the phenomenon using my digital camera set to 1/50th of a
second, and really see if fields are blended or not, so I don't have to
rely on my eyes only.
OpenGL still ensures sync, but not using XV gives a performance penalty
which leads to unacceptable skipping. I need to fix this video overlay
scaling issue before the filter I wanted to make becomes useful. I also
need to get MythTV to build, but that's another issue.
Is the snapshot in SVN more Fedora Core 4 friendly, or should I stay
with the 0.81 source release?
