This is what I have read from the dvdrhelp site a good few weeks ago and is from memory.

This is also from Memory. I have a book called DVD demystified, which was written by one of the first DVD authors. He said that the limit as specified by the DVD Forum is 10MBps. The DVD authoring systems we have at work (one of the courses I support is in DVD authoring) will not allow you to encode above 9.99MBps.
As I understand it, the forum specified that limit because the drives available to them at the time (1994-1995) couldn't handle any higher data rates.
