[mythtv] [PATCH] MythVideo cd support

[Xavier Hervy]

This version of my patch fix a bug that i introduce in videotree. before 
it, you don't be able to play video in videotree when "browse video in 
video list" is checked in settings.

Now it should work correctly.

Thanks to Jason Gabriele who found this bug.

PS: Matt Porter, excuse me. I wrote "Matt Potter" instead of your 
correct name in few mails ;-)
