It's a 2.4 Ghz Celeron, with 512 Mb of RAM, so it really shouldn't
have any problems playing XVids. From reading around though it's more
likely that I'm passing the wrong arguments to mplayer.

The default in Myth is something like:
mplayer -fs -zoom -quiet -vo xv %s

which doesn't work as Xvideo isn't supported using the PVR 350's framebuffer

I then changed it to:
mplayer -fs -zoom -quiet -vo x11 %s

Which gives me the slow video reported earlier:

Following something I found in an earlier thread, I then tried:
mplayer -fs -zoom -quiet -vo ivtv %s

In which case Mplayer starts, but never displays the movie.  I'm still
investigating this one.

I'm not sure which updated driver you're talking about, but I've
managed to get TV out working with both  0.3.2 (c) and 0.2.0rc3c.  The
main problem I had was that the IVTV X driver needed to be installed
separately.  I've so far tried one that I found at
http://membres.lycos.fr/badzzzz/ and also one of Axel's RPM's at
http://atrpms.net/dist/fc3/ivtvdev/.  Axel's one was noticeable
faster, but X is still painfully slow, which is casing problems when
you exit TV mode and it takes a while to redraw the screen.
