Video too dark in Flash OK in MPC

[jgg]

This is a really dumb little movie (only a minute or so) of some friends at a fish restaurant, but I'd appreciate some help, please.

When I watch the movie in the JWPlayer embedded in the page (newest version and the newest version of Flash), it's too dark - at least on my NEC 2490 and NEC 2190 monitors.

However, when I download it and open it in MPC, it looks OK - though of course it's still dark 'cause it was night, and I took the phone with my cellphone camera.

Why does this happen, and is there any way to fix it?

I'll appreciate any tips.

Thanks in advance.
