i juz got my macbook 2day...so was toyin wif it da whole day,then i copied some avi files from my old pc to watch,but sadly quicktime doesnt play avi files and front row wasnt playin anythin....so i downloaded some codecs(divx n sumthin i dunno,juz dl it),then fantastically it played avi file n even in front row......but da prob is it no longer preview on quick look coz it stalled n vlc even jammed in full screen mode...so can any1 help??

i think there are some issues with VLC and the new leopard. Google perian, it is a component for quicktime that runs (most) avi files.

hope it helps.
