Yes, this is because you're recording MPEG-2 shows, and then watching MPEG-2
shows. It works because it's MPEG-2, which your card knows how to decode.

That's because the Matrox card does not do any decoding, mplayer decodes the
data and sends it directly to the TV out - so you can watch anything mplayer

I don't think so, because your DVB card supports MPEG-2 only, think of mpegpes
as hardware ***MPEG-2*** decoding. If it's not MPEG-2, it won't work.

Yes, because film.vdr is MPEG-2.
> mplayer film.avi -vo mpegpes
No, because film.avi is *not* MPEG-2.

No, because MPEG-4 is still MPEG-4, regardless of what you resize it to.
I'm not sure how you do it with a DVB card, but I have a hardware MPEG-2
decoder card (a Hollywood+ or DXR3) and it works in a similar way:
mplayer file.mpg -vo dxr3
This uses the dxr3 output driver (which, like your DVB card, only supports
MPEG-2) however if I do this:
mplayer divx-movie.avi -vo dxr3
then divx-movie.avi is converted to MPEG-2 on-the-fly and sent to the decoder
card. This means I can play any file mplayer supports, and it will convert
it to MPEG-2 so that my card can decode it.
I'm not sure what you'd use for a DVB card (-vo dxr3 certainly won't work), so
I guess it's just a matter of finding the correct output plugin (I don't
think it's -vo mpegpes, because I think the dxr3 driver uses that
If you can't find it, you could try starting a new thread on this mailing
list, but make sure you use a proper subject - most people won't bother
reading a thread titled "Nobody knows", but they probably would read a thread
called "How can I play MPEG-4 through an MPEG-2 decoder card?"
