Yesterday I was setting up a new PC and everything went well, except one thing.
Trying to use the "Restore" function the program would not let me use files on another drive (I keep my database directory on an external drive, which I had moved over). I finally gave up and relented to doing a full setup, only do discover that the full setup option gives another opportunity to do a restore from a backup on another drive, and that process went flawlessly.
Oh, and one other thing. Initially on my Fire Cube the program icons for TV shows wouldn't update when programs were deleted, and new recordings weren't being shown in the recording directory. Closing the Channels app and deleting cache fixed that, or maybe it fixed itself.
One thing I couldn't figure out though was where exactly the backup files are contained in the database directory.
