[vdr] PAL- and NTSC-Resolution

[Dieter Poesl <Dieter@Poesl-Online.de>]

Hi there

Soory for posting this message again ... here it's with my modified 
mplayer.sh

After 12 years my tv-set died. So i bought a new one with NTSC- and
PAL-Support and 16:9 screen.

For watching Mpeg- and DivX-Files with Mplayer, i modified the
mplayer.sh (see below) Therefore my question:
Which XY-Resolutions are supported by the Siemens DVB-Card?
And which resolutions are scaled by hardware to fullscreen?

Thx

Regards
    Dieter
