Glad to see someone taking up this challenge. I have a rather large 
anime collection in MythVideo and using deep directories is the only way 
I can make things pretty. Tags sound like a good plan, and I like the 
"recently added" idea so that I can quickly tag newly added videos.

This may have been mentioned already (lots of noise on this thread), but 
what I really want in MythVideo is a way to do mass changes. To be able 
to select 100+ Naruto episodes and set them to category 'Anime' or what 
have you. I have found no way to do this in the current MythVideo 
without resorting to direct database changes. So, if you could keep that 
in mind I would love it. :-)

Sorry I'm not gifted enough to program these things on my own, so I am 
one of "those" people that has ideas but never helps make them happen. 
Personally, I happen to feel even those without coding abilities can 
still help by debugging and putting forth ideas.
