I have a Pentax WR43 digital camera and it too saves in .mov format.
Using BetaPlayer version 0.095, I'm able to play my .mov files on my X30!!
You can find it here:

If you rather convert the .mov to something anyway, a couple of ways to do it:
1. Use Quicktime Pro.
When you open the .mov in QTPro you have the option to export the movie as another movie format (like avi or mpeg)
2. Use TMPGEnc, a freeware video encoder.

Good luck!
