[Mplayer-dvb] ANNOUNCEMENT: mplayer.sh 0.0.4 ready

[Tilo Renkl]

Hi Arpi,

tested your latest chages to the scale filter. And I must say
it is looking very fine.

Only two things:

First of all, when I replay a 512x256 video, it is not automatically
rescaled to full width by the DVB-s card.
If I use : -vop lavc,expand=-1:576:-1:-1:1,scale=480:0,dvbscale
for example it works fine.

The second, and that really bad is this:
If I replay a 480x384 video, your filter calculates a new height
of 614 (!) and the mplayer say: Cannot initialize video driver !
