 I've tested this on two different sets of hardware using Mythdora 12.23
 and Mythbuntu 10.04 with the same result.  I wasn't able to find a ticket
 describing this problem.

 When I insert a DVD and go to Optical Disk | Play DVD, I get an error
 "Video frame buffering failed too many times."  I've tried 3 different
 DVDs.  The same happens if I go to Media Library | Watch Vidoes and select
 an ISO (tried 3 different ISO... different ISOs than the DVD movies
 above.)

Comment:

 ISO playback is not supported from Video Storage Groups.  See:

 http://www.mythtv.org/wiki/Mythvideo#Storage_Groups

 Only the "Video Frame Buffering Failed" is a valid portion of this bug.
 We need "mythfrontend -v playback" from trying to play back an actual DVD
 to learn anything about that bug/determine if it's a duplicate of one of
 the other bugs.
