I bought a region free DVD player today. I've been trying to watch some movies that are not region 1. Whenever I play them they go fine for awhile then they start to skip quite a bit. Is there a setting I must have on to make them work properly? I should also point out that these are bootleg copies (yes I know...bad Moon), but I'm not sure if that would have anything to do with it since my friend has the exact same DVD player as me and it works for him just fine.
