MPlayer supports X11 and Framebuffer output (I think you need a Matrox G400
for the framebuffer output to work). It does not support output through the
DVB card because the DVB card can only play MPEG streams. I talked to one of
the developers of MPlayer about this recently and he told me that output
support for the DVB card is highly unlikely. This is because the DVB card
can only play MPEG streams.
If you have an input file that uses motion vectors (like DivX) you can use
the input source's motion vectors and convert the DivX stream to MPEG-2
using these motion vectors. But DivX uses more sophisticated motion
algorithms (don't ask me about details; I'm no expert) that cannot be
converted/used in MPEG-2 streams. On a fast machine, it would be possible to
convert almost any input format into an I-frame-only MPEG-2 stream in
realtime but the resulting bitrate would be too high for the MPEG decoder in
the DVB card and most likely also too high for the PCI bus.
I recently bought a Matrox G400 at eBay and the framebuffer output with
MPlayer works fine (technically, read on ;-). However, MPlayer cannot resize
any input frame size to full screen resolution and will also not recognize
SVCDs properly. At least I didn't get those two things to work correctly.
Apart from that, there still is quite a quality difference between the DVB
card and my G400's TV-out (the G400's colors are less intense and high
contrast differences result in darker/brighter lines towards the right side
of the screen). It's the best TV-out I have seen so far and it's the only
card that is more or less well supported by the framebuffer system but it
can not keep up with the DVB card.
>From my point of view, the only practical solution for watching non-MPEG
movies on the DVB card is to transcode them offline and play them back
later. You might want to try ffmpeg (http://ffmpeg.sourceforge.net) to do
that task. It still has some problems with MPEG output but this is IMHO the
way to go in the future (unless someone comes up with a VGA card that has a
high-quality TV-out connector).
