Acts_as_list and a Join table ??

Hi,

I ve got two model, Video and Pack... My Pack model can have multiple
Video, and a Video belongs to multiple Pack...So i m doing a join
table, Video_Pack...
So my Models looks like :

Video :
ID
Name
etc.

Pack :
ID
Name
etc.

Video_Pack
Video_id
Pack_video

I would like to be able to order the video in a Pack... so i guess the
best solution is to use the acts_as_lists plugin... This way i will
have to use it on the join table, Video_Pack... so i've to add to my
Video_Pack model, the column Position... right?

Right now all of that is in my head, and i ve no idea if i m right or
maybe 100% wrong... so if you could give me an hand i ll appreciate a
lot,

Thanks in advance,
Guillaume.

Thanks for the tips,
anyone for the my acts as list question/problem ?

By the way Max, i m using more that the ID in my join table so habtm
is not working... i m using has_many with the through parameters.. so
i can name my join table as i want...
