Here's a list of videos that I've already converted to PSP. These have little to no errors in the cutting down of the frame rate. This will be updated as I preview and make more.

Note: Is it possible for a page editor to like, post links to these for me with a "Download These Onto Your PSP" on the videos or something, please?
I'll find more that look alright to be posted as PSP-viewable videos without any choppiness or with as little weirdness as possible in the transcoded video (during gameplay). One other thing I've noticed too is that the converter likes to chew out scenes where nothing is happening (The Amagon movie is a perfect example of it, because at the end of every level, it blacks out after one frame of Amagon standing still.)
I'll be adding more videos as I watch through them and see that they look okay to add up here to the list.
