...them in my psp but sum vids dont work? Im trying to use firefox's download helper app to download flv videos from mlgpro.com and youtube and then convert them to mp4 or avi and put them in my psp.(Ive already tried the MP_ROOT thing as well as just putting them in the video folder. most vids work but others show up as unsuported data. my firmware is 5.01. could the videos be protected or something?
