how to use custom post types collectively integrated with each other

hi
i will star with some back ground and my goal before i gt to the point

i am trying to make a anime viewing website using wordpress like http://www.watchanimeon.com and http://www.animedreaming.tv i tried a couple of techniques like tiring to use custom fields to store data but of no avail as they all got way too complected for a little guy like me .

i use categories for the anime series
and post for the episodes them selves
but for the part where i wanted my sits users or members to be able to add mirror videos i got stuck i came up with the half solution of my problem with wordpress oembbed feature or though to use autoembed in my template but the area where i wanted the ablity of mirror videos i tried to use tdo mini forms but did not succeeded because of knowing no means of saving this data in the post it self

then i came assross these wordpress custom post types and after the release of bbpress 2 it accord to me that if i could separate post types for series, episodes and mirrors (or videos) like in bbpress forums, topics and posts and have a series act like category then i will also be able to tag anime generas and the series will list the episodes associated with and every episode list the videos associated with it most of my work will be done but i cant find any way to do this as i told earlier that i am a little guy in the field don’t know much about programming and learns by google

so please help me plz plz
