is there any way to check what codec was used to encode a vid?
like i download sumthin off the net, and i want to know what codec was used because im not sure if the target computer will be able to watch the vid cos of the encoding?

the only reason i ask is cos i download sumthing for my gf, its about 160mb frm the net, i kinda need to know what codec was used because if its the right one then i dont need to reencode it so it works on her comp cos if i have to do that, the file wud be about 1gb! and that wont fit on any CD's i know (mind i said CD not dvd :p)
