[mythtv-users] Can't find A/V Decoder for DVDs

Sun Nov 6 17:54:05 UTC 2011

Thanks for responding, but I'm pretty sure I don't have storage groups
defined, and I'm also pretty sure I've decrypted the video.

On the backend when I run 'mythtv-setup' and select 'Storage
Directories' I see a "Default" and then a whole bunch of "Create..." 
(like "Create Videos group").  Doesn't that mean I don't have a Videos
group defined?

And when libdvdnav reports "

libdvdnav: DVD disk reports itself with Region mask 0x00000000. Regions:
1 2 3 4 5 6 7 8

Doesn't that mean the video has been decrypted and regions removed?
