Mp3Tag for Video

I would think that this topic has been posted before, but I have this fantasy that there is a utility out there that would be the equivalent of Mp3Tag for video files.

In my searches I have not located anything even close. Even a read-only reporting app that would provide basic information about the myriad of MP4s, WMVs, FLVs and other files that I have would be amazing.

I know that it's not on Florian's radar to create such an application, but does anyone have any recommendations?

TigoTago is a step in the right direction, better than anything I have seen.

Thanks for the head-up.
