Macbook Pro burning issue?

hey guys i have a quick question...

I do a lot of video editing and recently just created a video project. This video was created and burned onto a disk with a mac pro. i needed to create more copies at home so i used Handbreak to convert the disk file into an mp4.
when i view the project in quicktime as an mp4 (on my mbp), the images run very smoothly with no choppiness. But when i burn it onto a disk, the images of fast movement (ie, cars, people running) become very choppy and have that "matrix-ish" look (not in a good way). is there something wrong with my mbp? or am i converting it incorrectly? (from disk to an mp4/quicktime)

thanks

ya its ripped directly off the disk and i used idvd to create more copies... do you recommend downloading toast? and is this for sure not a hardware problem? im really hoping it isnt...
