Well
I have done video edition for a lot of paysites lately and I mosty convert from mpg and avi to wmv because that gets a file 75% smaller than the original one, and its played by windows media player without problems.
Some of them have both wmv and mov files,
I think the other formats are quite old fashioned and burn more than double of bandwidth, not counting DivX, but most surfers dont have the DivX codec installed, so I dont use it.
Hope that helps
Greetings
