MBJ, what info or advice can you give on upconverting from a 2.0 source to a 5.1 source. I know you've covered it in the past, but I'd love an in-depth guide on the process you used for creating your 5.1 master. I've tried following a guide at VideoHelp.com but it was fruitless in the end. Somebody needs to develop a simple program that will take a 2.0 source and convert it to 5.1. If it's matrixed, go with the matrixed info. If it's not, use whatever algorithm pro-logic uses to fake the surround and generate the streams that way.
