As a drum guy, I personally hyped hearing the drum judge's tape on the DVD the entire season. It's a cool thing to listen to after never getting to hear a tape throughout the summer, and just a bit of extra validation for the hard work put in throughout the season.
From my perspective, it's certainly disappointing to lose the extra video tracks (camera angles) and audio tracks (judges, designers), and I'll definitely be writing somebody a letter. Having the extra space taken up by the widescreen aspect would not affect their ability to throw the judge's audio tracks on there (the audio files being very small in comparison) -- they probably just didn't want to go to the effort to mix the judge tape audio with the corps production audio like they did last year (which was at times awkward, and also completely unnecessary). I mean, at the bare minimum, just throw an .mp3 onto the DVD's that people can listen to on a computer or through some easter egg on the DVD menu -- that would require minuscule disc space and effort.
The widescreen aspect wouldn't have been as much of a problem either if they had stuck with the 4-disc format they've been using the past few years, as well. Less content for the same price is bogus.
This year's DVD set does a disservice to the members of the percussion and color guard sections in the top 6 corps, but of course I knew these features were dropped and still bought the thing because my team is on the disc.
tl;dr amirite... /rant end
