Most people will convert them to another video format. Such as DivX or MPeg 1, 2, or 4 or avi. I'm sure others will be able to advise & the best ones, etc. & how to go about it.

For me, I convert the VOB's to a QuickTime video file & export/convert that with DivX which does a very good job at compressing but at a reasonable size.

At present I think the maximum sized file capable being shared on the network is around the 4 GB size. Most video files you find on the network are 600-800 MB or split into 2 or 3 at that size each.
