Actually Kevin had the right idea. You *can* mount the DVD and point
mplayer to the mounted directory. Here's how I did it...
- /etc/exports on DVD system (nfs server) (you cannot only export /mnt,
you have to export /mnt/cdrom or /mnt/dvd, or whatever)
/mnt/cdrom mythtv(ro,insecure,no_root_squash)
Then I just mounted the directory on the myth box...
mount -tnfs nfsserver:/mnt/cdrom /dvd
And in myth setup for DVD, instead of /dev/dvd as the directory, I used
mplayer dvd:// -dvd-device /dvd -fs -zoom
That seemed to work, *but* it's not very usable. The picture is great,
but the sound is about 3-4 seconds fast compared to the video. This is
obviously due to DVD playing over NFS. Still I would think I could
improve this and get the 2 in sync. Any ideas on how to do this?
