Yes, you can view videos on your PSP, but sometimes, those videos are in a different format and they are not supported by the console.
That's exactly when PSP Video Converter is useful because it can convert any video file to the format supported by your PSP.
It's easy to use and its interface is very intuitive. You only have to choose the source file you want to convert and pres the 'Convert' button, that's all.
You can preview results on a virtual PSP just under the main window.
Finally, although the name of the program only refers to PSP, it also converts video into formats supported by iPod, Zune and more portable media players.
