I have a few UMD movie discs that I want to dump and then convert into AVI - is that even possible?

I found this tutorial on UMD Ripping for 635 but not sure if it would work on 639 http://forums.dashhacks.com/f133/rip...per-6-t283820/

Of course no idea how to convert the PSP UMD over to Divix or AVI.

I have a PSP 3001 9g running 639 (I use the 639 PRO CFW).

Thanks.
