how does any user look for movies?
- newcomers will probably look at the starred movies. IMHO no hack or concept demo should be in that category, so everything's fine.
- regulars will watch NewMovies most of the time. category doesn't matter there, everything's fine.
- everyone looking for a specific game or just browsing will use the Movies-<system> pages, including the Movies-Hacks.
so IMHO, the organisation of the latter is the trouble here, and has been for a while for different reasons - for example, when obsoleting runs from different categorys or rejecting good runs because there shouldn't be more than x movies of this game published.
my suggestion is to change those pages into a more game-centric way: right now, they're already sorted by game names, but there could be a stronger grouping, including an additional Movies-<game> page which includes all the movies for that game (basically a different filter).
To avoid flooding the Movies-<system>-pages, those pages are only to display the main categorys for the game (as in: the most interesting movies), containing links to the game-specific filter with all the other movies - be it concept demos, hacks, gameplay with exotic limitations, or just obsoleted movies.
well, it's probably best described with an image, in this sample with one of the most category- and hack-intensive games: super metroid.

(please don't mind design/layout issues, broken character encoding or spelling errors)
This way, the concept demos / hacks category can be removed, as everything has it's place. Games with lots of characters / game modes can have lots of movies without cluttering the movie index.
There's also no need to put artificial limitations to run categories any more (like limiting SMB to the any% and 100% runs). Anything producing an interesting movie that's different enough from previous categories goes and can be published without littering the index.
As a consequence, no movie should be allowed to obsolete a movie of a different category any more, although the categories displayed on the index can be allowed to change.
oh, my definition of concept demo is "anything that does not complete the game".
(there's more to say about SRAM movies, but let's not spawn that discussion here)
