hey guys, I've been thinking instead of downloading the movies I already have, I could just rip them unto my hard drive. I rip an uncompressed copy (usually a whopping 6 gigs) but the playback isn't as good as torrented copies. The video is jerky, and often grainy. I'm using MBP 2.4 GHz, 4 gb of memory. I thought maybe it was because I was trying to play it from my external HD, but it was also choppy when saved on the internal HD. is it because an exact dvd copy is too much information for my mac to process?
