This happens when the system can't find the directories (and, therefore,
the file systems) specified by your Storage Groups.

I'd select Delete Forever and nothing would happen initially for most recordings. So I restarted the mythbackend service again, let it settle, then went back into the frontend to delete and had some success. I kept trying and finally I could Delete Forever each of the Deleted items.

I have no idea what's actually happening, but it sounds like some
file-system funkiness--like your file systems are appearing and/or
disappearing out from under MythTV (and, perhaps, taking too long in
some cases to reappear, causing a timeout/failure). Are you using some
kind of auto-mounter for these file systems?
