mythtv tries to use udisks to access DVD's or bluray's, but it's not a dependency. In addition, it requires an older version of udisks, not the latest. If the right version of udisks is not installed, it errors out:
Mar 5 17:17:15 localhost mythfrontend.real: mythfrontend: A CoreContext
mediamonitor-unix.cpp:198 (CheckMountable) MMUnix:CheckMountable: DBus interface
error: The name org.freedesktop.UDisks was not provided by any .service files
The ebuild should include a dependency on udisks:0, potentially conditionally based on whether or not use dvd or use bluray is enabled.
I see there are new mythtv ebuilds coming out, any chance you could address this dependency issue in one of them at some point?
mythtv 0.27.4 still needs udisks:0, just a ping as far as fixing the ebuild to depend on it. Thanks...
I have been haunted by the same problem.
As a side remark: After spending 4 hours on it, I have found the media monitor of mythtv to be quite week.
For me it required an entry in /etc/fstab. Without the entry it would not mount the DVD disk.
Furthermore, after automatic detection of disk and mounting, the screen with the newly mounted medium is shown, but when trying to play it, fails miserably after waiting 10-20 seconds.
I realized that there is a better way by letting something else automatically mount any pluggable device. The mount point should also be added as additional directory to "the Movies". Movies accept list of directories. Unfortunately mythgallery doesn't.
I use XFCE and it's automatic mounting.
I don't really use optical media with mythtv either, but just for the sake of correctness it would be nice to get the dependency fixed.
This will be fixed with the next bump to 0.27.5. Sorry for the long delay on fixing this issue.
Thanks for the report. Fixed in http://gitweb.gentoo.org/repo/gentoo.git/commit/?id=9ada29b52010e465a522fdc68d4eee0da6eaa349
