@ michaeldc: This would definitely work but the problem is, that the limit in all the programs I could get my hands on was 6-8 tracks, not 16. But I asked around and I might actually get access to a computer with pro-level authoring software through school, so I'm holding out for that. Another thing is that I've never done BD authoring before and it seems far more complicated than what I've done with DVD (and even that was quite difficult for me) - I'll give it my best shot but the ideal situation would be if someone with access to the necessary software and the skill to do it, would be willing to turn my designs into reality for me.

@AK-47 - I believe that that info applies to v2.0 - I hope I remember correctly, but I think that in v2.5, all the tracks are fine.
