I just had a thought... my TV seems way more capable of
deinterlacing/scaling than mythtv. I've accidentally set my Xbox 360 to 720p
and left it that way for months unknowing. Over dvi-hdmi with mode
1920x1080_60i, mythtv can playback 1080i content w/o any deinterlacing. It's
480i content that is giving me a headache. It's the upscaling to 1080i that
is multiplying the interlacing artifacts, I suppose. I'm going to try
setting it to switch resolutions on the fly, because I just realized THAT is
what my cable box does.
I only came to this realization now because it wasn't till last night I got
1080i content to look decent at 1080i output. I had to DISABLE opengl
vertical sync (or whatever it's called). That got rid of almost all the
jumpiness. There is a little studder during commercials and such, which I'm
guessing the opengl sync option is supposed to fix.
