The directories it contains might not have.
Or your browser drops privileges/capabilities before it executes the script.

Python expanduser falls back to parsing /etc/passwd (or equivalent) as a last resort.
MPlayer only looks at the HOME environment variable.
So I'll just repeat: you need to ensure that MPlayer gets a proper environment.
I web server is not _supposed_ to be able to run a full media player for security reasons, if you insist on that you will have to fight against all these and will end up with a system that is much less secure as the minimum expected of a web server nowadays.
