I have shared DVDs across my network and am using an NFS mount to play
them back. Here is how to do it. The key is to let the local system
handle the decryption so that MythTV never has to deal with it.
1) You can copy a DVD using dd to the hard drive and share the
directory that that DVD is in via NFS. MythTV will play this back fine
and handle the decryption for you too. The trick here is to use lsdvd
on the drive before using dd. So something like this:
a) insert DVD but do not mount it
b) use lsdvd to decrypt
c) use dd if=/dev/dvd of=/var/bigdrive/dvd.iso
2) The other way to do this is similar to the above but without the
copy:
a) insert DVD but do not mount it
b) use lsdvd to decrypt
c) mount the DVD on the exported directory
It's no where as neat as the Apple DVD drive sharing for Air Books but
it does work.
