Portable(USB flash drive) DVD player software.

Looking for some DVD playing software that does NOT need installed, and can completely run off a USB flash drive. Region free, etc... prefferably.

I tried copying PowerDVD over, but it would error out when trying to play anything, even manually playing VOB files.

Don't want to use WMP on the PCs themselves.

I believe VLC can be portable, and I know it can play DVD's. Check it out:

Hrm, looks like it might work. I'll download it when I get home from work. Thanks.

Also looks like it supplies the source, too bad I can't program
