Has anyone else experienced this?
With MythTV (and assumingly other programs as well) it has been possible to watch a ripped DVD iso file directly - but the last couple of weeks nothing happens.
The error is about the drive not being seen as a DVD - and I noticed something 'funny':
If there is a DVD (here KillBill) in the drive, and I select to watch an iso-rip, the DVD is played instead of the iso-rip (the iso is previously recorded television programs with the kitchen chef Heston) - so it appear that some program in the chain fails to redirect the request to the iso file and use the dvd.
I can see that dvdnav and libcss is in play - but not sure exactly what program does what and where to report the issue (clearly a program bug somewhere),
