An example of what I mentioned earlier would be this: "MM! NCOP1.mkv", so in the record itself, it would be something like C-something or other, is that correct?

So, if you look on the site, you'll see on the MM! show page a listing of OP1 Help!! Hell Side (1-4). Click on the OP1 link and you'll see Episode: MM! - C1 - Opening 1 at the top of the page.

C1 -> S101, so for example:
"MM! S00E101 NCOP1.mkv", or
"MM! 0x101 NCOP1.mkv", or
"MM! - S101 - NCOP1.mkv" (with the regexps from the first post)
would all get the file added to XBMC.

Interesting... It's just that I've used Filebot most of the time to rename my anime files and I always thought it had a problem when it came to renaming extra's.

I take it that I'd have to rename things like OP/ED/Trailers, etc. individually according to the AniDB listings because Filebot couldn't do it properly or at all?
