Yeah, tha'ts what I got. Sandisk 1GB Memory Stick Pro Duo.
I've looked around a while ago to find a way to imprint subtitles into the mp4 file. Most of them showed a long and complicated way to do it, so I've decided to buy a PSP Movie Maker. Now with that pspcraze.com website, theres a good tutorial in there that shows you how to do it. I wish I've known about pspcraze.com!

Well, at least I know now ha. Here's the tutorial if you guys want to know a quick and easy way to paint subtitle to an mpeg4 file.
