Creating PSP vids from DVD & downloads

I'm looking for advice on ripping and converting movie files for my PSP. I have PSP Media-Manager, but just getting files suitable for that to convert is my prob.

1. DVD's. What software to rip with? I know about using DivX to create AVI format, but is there an issue with codecs? Any other alternative softwareto DivX?

2. Downloaded files from the likes of LimeWire etc. These are usually DivX and sohave codecs and so PSP M-M doesn't convert them. IfI get DivX, will that automatically give me the codecs and thus let me convertusing M-M or some other software (which?)?

Thanks in advance to any experts out there who can help:D

Thanks very much SS35 - I checked them out and I think that takes care of my DVD-ripping. Also got some good alternative software links off the PSPVideo9 site.

I now just need to understand how to handle the DivX files I download from P2P sites.
