I have 2 problems with uploaded files.  I'm using IE9, Win 7 SP1, and Silverlight is installed. I have uploaded and tried to share these files

The first is a 168MB .mpg4 file. When I try to play the video it is broken up and jerky, unwatchable.

The second is a 400MB .mov video clip. When I try to play this one I get a message, "It is not possible to play this file..." (or words to that effect) and suggests downloading the file.

Are these issues to do witht the file sizes? If so what is the limit?
