That's exactly my point, 16:9 goes off the screen, it doesn't
matter if
it's the desktop or Xine.
All s-video out graphics cards generate an analogue signal, just
because
you're using the same modeline with the new card as with the old one
doesn't necessarily mean that the picture will appear in the same
place
on the tv/monitor. The modeline controls the pixels x-y, the physical
width-height and the x-y positioning on the screen, but it's all
relative due to inconstancies in the hardware.
Remove all the modelines apart from the ones you need, find a good
modeline explanation on Google and start tinkering.
Adjust them a little at a time and with a bit of work, you'll be
able to
tweak it so it's perfect.
I understand what you are saying, but could you please explain to me
how or why Myth is switching to a different modeline during video
playback? It shouldn't be doing that should it? The modeline I'm
running is 4:3, and the picture doesn't go off the screen when viewing
the X desktop or the Myth UI. Why would it suddenly switch to a
different modeline for video playback? Shouldn't it just scale the
16:9 video to fit the 4:3 modeline?
Is it the Myth video player or Xine? As I understand it, if you try and
view 16:9 content it will change resolution, rather than rescale the video.
Your modelines say that's OK, so that's what it's doing... If you don't
want it to do that, then remove the modelines (except the 800x600) and
it won't be able to...
