This has come up in a different thread, and the solution people seem to be happy with is this product: DVD and video to Blackberry - only two clicks needed
Also, here is a direct link to the ongoing discussion over there: http://www.blackberryforums.com/gene...tml#post554218
With that being said, there are open source DVD rippers out there, open source encoders out there, but you would have to go and get all the pieces yourself and configure everything to work with eachother and then the BlackBerry. The produc above is a direct, made-for-Blackberry turn-key solution. But as always, ready-made comes with a small price.
