Keeping it at 480p is understandable. Are you still putting two versions (filtered and unfiltered) on one disc or have you given up on that idea? I just can't get over how massive the overkill involved in what you are doing is. If I were you, I would simply make a DVD (a DVD-9 if you are worried about quality). I could show you exactly how to do it, but I know you have your heart set on the BD idea, so...

If upscaling does become necessary, there is a thread on it here. The method that Antcufaalb outlines is basically the one I use, and I don't know of a better one.
