Size and format of video for the paysites
 

Which format and sizes of videos will you recommend for use on paysite (single girl site)? Or what is the standart for these paysites?

I guess:
formats: wmv and mpeg (for mac)
resolution: 640x480 hi quality and 320x240 low quality all in one piece and whole video (cca 8-12min) in 4 pieces.

Thanks for any advice :)

I'd be interested, too. Anyone?
