XvMC = X Video Motion Compensation = the stuff that allow Xfree86 video 
drivers to directly access the hardware to feed it with MPEG2 streams 
(or so). MPEG2 decoding is mostly hardware, then.

Use daemons for this stuff. There should exist.

I stiff have to configure this, but the mplayer plugin is basically an 
interface that allow you to select a file, then run an external command 
with this file as parameter. The command is mplayer.sh, a script that 
takes configuration parameters in a file, and run mplayer with lots of 
options. The default conf uses the FF-DVB card as output, but you can 
change it and user DFB or Xv - whatever mplayer has.

It' much more fun to tune a driver than to barely watch idiot shows on 
average TVs.

DXR3 is basically the MPEGS + OSD output of the FF cards, upon which 
VDR's output model is done. So the X or terminal plugins should work 
there. Simply don't expect something marvelous, because you will be 
limited to the OSD resolution (640 x 480 @ 8 bpp or so), and it should 
be slow.
