No. Because SMB won't transfer authentication requests ioctls and others.
Maybe you can try nbd (Network Block Device) in Linux. Or you can try the
following (but you should run Linux on the other computer too!):

Run mplayer -dvdauth /dev/dvd /mnt/dvd/video_ts/vts_01_1.vob or similar
on the SERVER. Memorize the title key.

Go to the client computer, mount the video_ts directory through eg NFS.
Then issue the following command here:

mplayer -dvdkey 0102030405 /mnt/nfs/vts_01_1.vob

where 0102030405 is the DVD key.
