That doesn't make any sense.  I don't see the content being mastered for 
BOTH dual-layer discs (~4 hours) 
and single-layer discs (~2 hours).  You'd be mastering for BOTH formats, depending upon what people send?  Err...
And I certainly don't see the contest getting close to 16 hours worth of videos (approximately 4 discs times ~4 hours per disc).  In the years that I've submitted (2002-2004), it's never exceeded three 2-hours tapes/DVDs.  It's highly unlikely that Pro will amazingly and suddenly receive a more than 200% increase in submissions, especially where it's only limited to one entry per person, these days.
Four single-layer discs, which will probably hold under 2 hours per disc.  It's ridiculously unlikely that there's a need for anything beyond that.  I mean, especially considering the price and NON-compatibility with general set-top players when using consumer-brand dual-layer DVDs...
