ok so it's trying to open /dev/mga_vid vo_mga

couldn't open /dev/mga_vid...Error opening etc
However at startup it says
"Playing dvd://1.
reading disc structure etc etc
DVD Successfully opened"
I've rtfm'ed the m, but I'm still in the dark.
I've changed the video and audio codecs to the ffmpeg family but that didn't make any difference.
Whats this mga_vid thing? Shouldn't it be someting like dev/cdrom or dev/dvd?
