Trying to do something with a LNxxD403

[Schiphol]

Hello,

I have a low-end LCD. The full model no is: LN32D403E4D

I have been reading the wiki and the forums, and I've formed the impression that I'm pretty much stuck with the official firmware. I just wanted to ask here, in case more knowledgeable users of the forum might (hopefully!) prove me wrong.

To clarify, I'm mostly interested in playing video files from the usb port -- who isn't, I guess.

Cheers,
Manolo
