[Mplayer-dvb] newbie question about scaling and positioning

[Uwe Weissbach]

I try install and using mplayer over dvb
but I'm not satisfied with scaling and positioning

Here are some samples:

This first movie (576x304) is scaling to
a strange value (576x766) and mplayer
put at the left side  of the screen so I have
a big black bar on the right (no bar at left).

The second movie is the same,
the 544x320 goes to 544x810 and
the movie is too much at left,
it seems there is missing a piece on the right side

The third movie seems to be even, with strange values
(512x864) but everything is ok and the positioning is fine...

what's wrong ???

mplayer is 0.90pre8
linux is 2.4.18 (suse 8.0)
and dvb-driver is 20020709

mplayer options are: 
-ao mpegpes -vo mpegpes -vop lavc,expand=-1:576:-1:-1:0,scale=-1:0,dvbscale


thanks in advance,

Uwe Weissbach
