[mythtvnz] DVD doesn't want to play in a bluray player

[Douglas Pearless]

Since adding a USB bluray player, I can not longer play DVD's in either my IDE DVD player or the USB Bluray player. 

In both cases it seems to try and load the UDF file system and then fails to read the disk, e.g. 

[447025.646044] UDF-fs: Partition marked readonly; forcing readonly mount

Any ideas?
