Oh wait, video module and photo modules are creating albums; and that is going to throw a spanner into the works; and other things as well. HL is correct, not so easy. Videos and Photos and Sounds share the same tables for the albums; you have the album table that stores the album ID and owner and then you have the album objects table. Yes, going to be messy.
When you click on videos, it pulls out all the albums for that particular user and shows them; there is nothing to indicate it came from this video module as oppose to that video module; so no matter which video module you clicked on, it would pull out all the video albums.
However, for what you want, that is the purpose of categories.
