Need help with Jcow video module

Hi all, i'm not very good at php, i need help to guide me modifiying jcow's video module, adding 5 star rating feature and enable embedding from another site other than youtube

about jcow --> jcow.net
about the 5 star script in my mind here


actually what i wanted was to make user can share embedded audio player instead of videos.. with ratings.. but thats more complex i guess..

thx
