I downloaded a tv show season and the episodes are named 1, 2, 3, etc and I'd like to change them to 01, 02, 03, etc so it sorts in the correct order. The actual file names are 01 but the XML is not. I see the XML files and have edited them, but they keep getting re-written to the original information.

Is there an easy way (GUI not command line preferably) to edit the episode numbers so the changes will stick?
