help building new free hosted video sites

[chilihost]

I am going to be building new free hosted video sites, I need your help deciding a few things:
- is one warning page, one enter page plus two video gallery pages good?
- is it best to feature one video's teaser clips or two (one per video gallery) or more?
- how long should the clips be and how many per gallery, ie, 10 seconds x 10 clips?
- I am assuming standard mpeg clips are best?
- any other advice to make this succeed?

thanks,
Luke
