[Mplayer-dvb] newbie question about scaling and positioning

[Martin Hoffmann]

Have you tried my (inofficial) mplayer dvbscale patch, which does only use 
some dedicated x resolutions, since all others did not gave me full screen 
picture.

You can find it at 
http://ma.hoff.bei.t-online.de/patches/mplayer/dvbscale_patch.diff

Please report if this did help !

Btw: Do you use an Rev. 2.1 DVBs Card for output ? this phenomenon was only 
reported on 2.1 cards so far!
