v2.5 Issue (Please Assist)

Please help!

I have upgraded one of my sites to v2.5 and when I use the import video feature inside the admin area I get a white screen. I am not referring to the import folder. I am referring to the import video and not the folder.

Basically, when I input the information and press submit the screen does white.

This is what I have done to resolve, but with no Success:

1. Uploaded all files again in Binary
2. Reinstalled entire site from scratch

Neither of these fixed the problem.

Lastly, I am using PHP4 on my server and not PHP5. This cannot be change as I am on a semi dedicated server.

Please help!
