Different Video Player?

[Insatiable]

Okay, so I had several videos that on my pc - I downloaded from youtube and converted to mp4 - Ipod compatible. I had them on my storage card in my Pro and WMP played them just perfect. No issues.

Now all of a sudden its stating that the file is corrupt or the extension is not recognizable and wont play any of my videos except one thats a wmv.

I also have WVD downloaded and it wont play those videos that I download that way either. Is there another video player thats good for the PRO and wont take up a lot of memory!? I miss watching my videos!!
