If you are new to DVD encoding, as it seems you might be, there are many other programs which are much better now.
DVD Shrink
Pocket DivX Encoder
Beta Player
are all you need now. You simply rip the DVD files to you hard drive using DVD shrink, rename the largest .vob file to .mpg, and then run it through PocketDivXEncoder. You then use beta Player to view the file created by PocketDivXEncoder. It isn't hard at all, and you can get pretty good quality for with small size files too. To answer your question directly, your X30 may be able ot handle the increased bit rate, but it would also increase how much space you would need on a storage card. If you stick with the 3 programs listed above, you will have good quality films at a lower size. Finally, do a search on this kind of topic. I mean, we get multiple new threads on how to go from DVD to Pocket PC every day. Just do some research first, then ask if you can't find it. (Gosh, I'm turning into gsteinb88 aren't I?)
