That's not true, the main file itself should fit on a BD-R (without the extras). The main issue is that it's not BD compatible and your player may or may not be able to play it.

I'm going by what waspattck said above in regards to the file size & burning to a Blu-ray disc.

That's indeed the main issue. I prefer to watch films using the bluray player and projector, when possible, rather than have to use the computer and take that downstairs. I'll try a variety of options once its downloaded to try & get a playable and compliant bluray starting with magicyuv.
