Strange DVD Studio Pro 4 problem
 

I made an HD DVD in DVDSP 4 with a standard HD menu provided by the software, and I burned the disc.

When I played it back on my Mac, the menu wasn't the HD one, but an SD one. Not only that, but the DVD was exactly one that I had made just the other day to show people on SD DVD players.

Any idea why I would burn an HD DVD with a green menu, and end up with an SD DVD with a black menu, made earlier?

Also, I'm on Panther OS X 10.3.9, with a single processor 1.6 ghz G5. My one theory is that I'm not using Tiger.

Thanks,

heath
