ok.. origannaly I planned on getting a psp just for commercial games, no homebrew or even video features ( got my gp32 for that ). nut after watching some of the previews on the smaple disk that came with it, I was BLOWN away. I quickly encoded a small 1:30:00 long commercial me and my friends made in school and was even more blown away. Unfortunatly, that took up 19mb of the 30 on the mem stick that came with the psp. I encoded it on the highest setting in PSP Video 9 though. Anyways, How big of a memory card should I get to watch full length movies on? I saw that 256mb ones wer $30 on circuitcity.com but then 512mb ones shot up to around $70. Would a 256 be alright for movies?
