Ok guys I just made the switch to the mac and so far I really like it but alot of my mpeg files and jpg files I had stored either dont run with sound, or stutter(mpg) or just dont show up through preview or I photo. Please tell me which is the best .avi-divix player, and image viewers. Also any suggestion on a good p2p would help. One last thing, I only use OS X how can I delete OS9 to make more room on my harddrive?
