PSP is the classic Sony console that apart from running games, also allows you to play all kinds of videos, but unfortunately only in the native format of the console.
PSP Video 9 however allows you to convert any video format to PSP. The program has a wide variety of options that lets you select both the quality of video and sound and it includes an administrator to copy video created directly to the console. All you need is a USB cable and your PSP to transfer files to your console. However, as you'll see in the developer forum, nothing goes quite as planned with this program. Although files are transferred, frequently you won't be able to watch them which is what a lot of users are reporting. One of the problems is that files will frequently appear as 0KB and the developer suggest that it may be because your PSP memory is not "clean" enough for the program to need. What you'll need to do is reformat your entire PSP memory card which is a drastic step but seems to be the only way to get things going again.
If you've got a PSP, and want to watch movies and clips in other formats, this is an option although you may find it hit and miss.
