No limitations as far as I can see. I have tested the created Blu-ray structure with PowerDVD and everything seems fine.

I know about the safe areas, but didn't care, since I turned off the overscan on my LG TV. You are 100% right though, so I changed the design a bit in my final encode. A good idea anyways, since I am planning to burn it to Blu-ray for a couple of people...

I haven't tried it so far, since my version only has 15 audio tracks, but I'll test it as soon as I can. That would be a bummer...
