Newgrounds is still a little finicky with my mp4's, but I'll get it figured out... I'm using the same settings as all the previous videos, perhaps something changed without me noticing it?
Thankfully, one of the coolest things about Newgrounds is that it makes collaboration easy. To rule out the possibility of it just being that my internet sucks too bad, I'm having MetalRenard (who has a fast connection) upload the file via the project management system... if the file refuses to upload for him, I can narrow the problem down to the file rather than packet loss during upload.
