more is always good. 2gb should be fine with xp. although is the movie is glitchy I suspect you have a slow pc in general. try another video file to see if it plays glitch free. better yet try this:Download this movie file frome here: (It's an HD movie file about 80mb)
http://download.microsoft.com/...0.exe
you have to run it though. If it can play that then you should be fine.

so i'll have to watch that video some other time. however, i've never noticed any kind of videos getting glitchy until recently when i started downloading entire movies. my comp has a 1.6 gig amd turion processor (dual core) and a nvidia geforce 6150 video card (which i hear is probably built in to the motherboard, so it can't be replaced). my buddy did mention that the glitchyness could be cuz of a shitty video card.
