No problem, I've never used the software you mentioned so I don't want say one is better than the other without some first hand knowledge. I can say that Ripbot is pretty powerful but hides a lot of the complex stuff behind a fairly simple interface. It's there if you want to dig, but it's also very easy to get great conversions without ever touching any of it.
RipBot264 v1.16.2 - Simple and easy to use GUI -> IPOD . PSP . CONSOLES . BLURAY - Doom9's Forum is the link to download it, it's always updated with the latest version and is also filled with tons of information on settings etc. Alot of it is way over my head so don't feel to overwhelmed if you take a look at it hehe.
If you want some settings after youve taken a look at it let me know and I'll be glad to pass some along.
