Title: Raise an error for unknown video size

Check for NaNs in video metadata (try encode with encoding.com into MP4 and default MPEG4 video codec and play to see the problem: "METADATA RECEIVED: NaNxNaN"). Should raise an error. Currently plays audio but no video picture - dark screen.

Just to eliminate confusion :) Or maybe add something like "Use H.264 instead for MPEG-4 Visual to be able to play with Flash" into the docs
