It's 7:18am on Sunday morning. Wanna help me with a regular expression? [View all]

I know this is a total long-shot, but if anybody here would like to help me test the monster I wrote last night, then you can do it here:

I've spent a while trying to break it with mistakes one might make while naming a file that requires a naming convention (e.g. typos)

I'm using it to rat out bad filenames before I queue them up for transcoding in ffmpeg. The files are screened for bad extensions and bad MIME-types before they hit the expression, which I can't post here because of smilies.

There's info about the naming convention and what is supposed to match/not match at the link.

Thanks!
