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?
