It's been an ongoing project for me for the past YEAR trying to get
mplayer to play my movies out the video output on my Miro DC30 Zoran
based card. I know the card is in working condition as it works fine
on my G4. I'm now running Slack 10.1 with a kernel that I
built myself. I'm able to get the driver for the card to load in fine.


modprobe zr36067 card=3 debug=4

BUT whenever I try to get MPlayer to use it, I get stuff like this,
and no video.

mplayer -vo zr -v "Dancer In The Dark.avi"

zr: error waiting for buffers to become free
zr:error queueing buffer for playback

I'm thinking there still could be problems driver-side, and I haven't
been able to find any good step-by-step instructions on actually
making use of one of these cards. Any ideas?
