[mythtv-users] display resolution switching still not working

I believe all 1080i content is encoded at 1088 because of something to do
with the mpeg standard.

Ok, ignore previous message from me. I wanted to be sure the switch
resolution was working so I enabled verbose on playback. It appears it was
still switching to the 888x508 because the video was recorded at
1920x1088 for some reason and I only had 1920x1080 in the setup as one of
the alternatives. I added 1920x1088 as the second alternative and set it to
switch to 1920x1080i. I restarted X and it starts in 1920x1080i then
mythfrontend starts and it changes to 888x508 and looks ok. When I playback
the 1920x1088 show it flashes black, then the desktop shows, then the upper
left quarter of the recording plays in the upper left corner of the desktop.

On that note, maybe we can have the code that checks for the width and
height of the video to determine the screen size to switch to do something
like if Width is >= to set option and Height is >= set option then switch
resolutions. That way if the video is recorded as 1920x1080 or 1920x1088 it
will switch if the setting is 1920x1080. That would still leave the second
option open for other resolutions.

Let me know what else you might need. Running FC1, XFree86  release 4.3.0,
KDE desktop, NVidia driver 6111
