Also I just put this on my PSP and watched it.

Instructions: The videos are in AVC format so you'll need to have firmware version 2.0 installed. If you wish to watch the videos simply go into the videos folder, select the desired title, and transfer both the mpeg file and its accompanying .doc file into the "200ANV01" folder of your PSP. For music, you may simply transfer the entire folder over to your "MUSIC" folder on the PSP. Note that the audio is in AAC format. The pictures can be transferred directly to your "PHOTO" folder on the PSP, no specific firmware is required to view these.

Or you can just watch them on your PC without worrying about upgrades.

Damn it you need 2.0. I might upgrade to 2.0 for the browser or use a hacked version.
