I've never used/heard of either of those programs. But PQ DVD is very well spoken for around here, and is very fast. Just check to make sure your audio stays in sync with the 5 minute trial before purchasing. I am however unsure if the videos play on the PSP or how they would look.
i use riversofts crazi video for ipod as it has crazy compression while keeping the quality up my 250+ mb .ogm animes get down to around 75 mb with no noticeable quality loss cucusoft made the audio screechy which wasnt cool. however i dont believe it has dvd support so id use cucusoft for that.
I dunno if anyone's heard of this, Total Video Converter... it rips dvd, it converts from everything to evrything (flash videos, gifs, mpegs, avis, mp4's movs, qt's, asf, swf's) so I use it. Plus, it has a great speed!
