Hi Guys

I have a Pc with 2gb Ram, Nvidia Graphics Card,Amd Processor 2.? Ghz,Motu 828 mk 2 my sound card
120 gb Harddisk.
and lot of vst plugins

when i import a video file (size 166mb) mov file it syncs but
starts playing with glitches and when i import mpeg file it goes offsync. I tried all the options. changed the settings in the video options according to the file type still i was not able to crack it.

my other friend works on a lower hand set up with 1 gb ram etc but still he can play the mpeg properly that to a big file of 600 mb
