Reading a DVD (movie) over NFS

[Kieren]

I want to share my DVD drive on my desktop with my Eee PC using NFS. I have set up NFS without any problems but I can't watch any DVD's.

I have mounted /media/cdrom and I can see the files on the desktop DVD drive.

When attempting to play the DVD over NFS using VLC I receive a loud screeching noise but it does play for different durations of time which I'm guessing are the DVD's chapters)

Any hints or suggestions?

DRM/CSS - do you have the libdvdcss package installed on the Eee PC?

[Kieren]

Yeah, both computers are running Ubuntu (and Kubuntu) with restricted-extras installed including CSS packages

[Rubberman]

Since you can see the directory structure, can you run one of the VOB files directly with VLC?

[Kieren]

They all produce the same screeching as when playing the full DVD. Let me try and run on the command line to get some output...

[Rubberman]

I could be the latency introduced by NFS that is causing this effect. Also, I think that the CSS decoding has to be done at a low level and might not work for a remote drive access like this. Not sure. Just swagging.

Okay, the screeching is no longer happening and now VLC just opens and does nothing. Here is the stdout:

Can you view the DVD on the desktop/host machine that the DVD player is attached to?

[Kieren]

Yes, that works fine. Attaching the DVD player (it's an external) to the Eee allows me to play the DVD without errors too

[Rubberman]

Then the problem has to be related to the remote access aspects of the situation. What if you use dvdbackup to rip the DVD to the file system (it will remove the CSS DRM) and then try to play the movie?
