The state of Blu Ray on Linux / MythTV

The DVD drive in one of my MythTV machines has given up the ghost. I have to go to Fry’s tomorrow to replace a dead hard disk, so I’ll pick up a new drive while I am at it. I am surprised to discover that Blu Ray drives are now just $90. I wonder what the state of Blu Ray playback on Linux is like at the moment. How’s the MythTV support? Time to find out.
