Don't know if this is by design, but the Bulk Rename form only loads movies that have the field NfoPath set.

I've used that as trigger to prevent unscraped movies from renaming. My point was: if a movies isn't scraped than also the most or all information for renaming are missing. But that's a problem in your case... I've to check, how a change would affect automation (e.g. if a new episode without an NFO will be added).

I've also found the bug for the root folder rename. It's a problem that starts with a Directory.GetParent call, but also has to be addressed in several other points in the code where you .Combine paths and file names to issue the move command. If you want I can try for you. 

Found the same bug, also other ones. I've a complete re-written renamer API in the pipeline, so I wanna change only whats needed to fix the issue.
