I am having problems with using Handbrake and VLC. I am using a MacBook Pro (2.4 GHz Intel Core 2 Duo) and when I try to use Handbrake it tells me I need to download the appropriate software for it to work, ie 32 bit handbrake to 32 bit VLC and 64 bit to 64 bit. I have downloaded the right one 64 bit, but it still doesn't copy the DVD well. There is a lot of skipping. Any ideas on how to fix this problem?
