It's the DVD-Rom.
Not the disc. If you play that "Multi Angle" DVD in a regular set-top player, you won't encounter that. I asked myself the same question which you just posted. The result was the DVD-ROM. Remember, a DVD-ROM will never perform better than a regular set top player. The only huge advantage a DVD-ROM has is being fast when it comes to layer changes, which right now, it's not even one second. That is pretty cool, but that is about it.
DVD-ROM were never created for movies since the start, it was meant for programs and games. It turns out being that they play movies..they might as well commercial that which generates sales.
P.S: Try playing "Cable Guy" in a dvdrom..the widescreen side, no DVD-ROM in the world plays it. My Buttman At Nudes A Poppin #10, the special features don't play on my DVD-ROM but on my super Sony 560D, it plays flawless.
