Hi people!

Now this is really strange. I managed to play my first avi file ever today after downloading a long Chris Rock special through LimeWire. When I was using Kazaa I had downloaded a few movies (in avi format) but with no luck in trying to play them. How come the problems have disappeared? I haven´t installed any codecs or any other players, I simply played the file in WinAmp. The picture was terrible but still, it is a progress.
Anyway, I´m downloading some movies right now, do you all still recommend these codecs? In that case tell me where to go. I´ve tried a few links but they were either invalid or there were costs involved.
