Facebook doesn’t support premiere pro files, and I tried converting them into avi files but they’re too big (they have to be under 300 MB). How do I make them smaller without losing all the quality?

Up until recently, a i used to be able to listen to a song on a music blog by clicking on the link and it would open a new tab to play in…now it opens my windows media player and plays it that way. im sure how this happened but i dont like the fact Windows media player is opening everytime. (not sure if it helps any, but i have windows xp)
thanks.

I have like the super latest version of psp like 3.4 or whatever and I am trying to learn Japanese on my PSP. There aren’t alot of podcast or you tube videos but there are alot of web pages with sound files. How do I save these on my psp without having to log back into the net.
