text: macs vs. pcs? i use a mac at my school to edit and transfer my short films. when i try using windows, i get dropped frames and the sync of sound and video is off. i've tried adobe premiere and windows movie maker. is there a way to fix this?  pc specs: windows professional sp2 intel pentium 4 2.26 ghz 512 mb ram 80gb hdd nvidia geforce4 mx 420 first, make sure you have the latest nvidia drivers for that mx 420, if you don't, install the current version and see if that helps. if that doesn't help, since i don't have any more info, the problem could be due to the fact that the mac you're using has a better video card than the one on your pc, as the mx 420 is a rather low end card.  you can get the latest drivers here:  http://www.nvidia.com/page/home.html
