[Frameworks] combining SD and HD

[Aaron F. Ross]

Sadly, on this list there seems to be a lack of technical 
understanding of basic principles of digital art. "Up-res'ing" or 
resampling resolutions is a really bad idea. You'll get fuzzy, crappy 
video. Don't do it.

As Freya said, you can store different resolutions of video on the 
same Blu-Ray disc. The only requirement is that each be a separate 
file. If they are all different titles, than this is a non-issue. You 
can see this in action on many commercial Blu-Ray discs. The special 
features, such as interviews, are often in Standard Definition. This 
is not at all a problem to author. Just be sure that your files are 
each encoded correctly to the proper specs. Otherwise your authoring 
program may re-encode them, to your dismay.

Regarding Blu-Ray authoring, please forgive my apostasy, but Apple's 
tools are clearly behind the curve. I use Sony DVD Architect, and it 
is relatively bulletproof. If you're stuck on the Mac platform, you 
might take a look at Adobe's offerings.
