Interesting conversation. I'm not annoyed by trailers, but I do appreciate being able to skip them (and I've never encountered a title that wouldn't let me skip. Usually not fast forward, but skip yes). I have to agree that renting discs is pretty cheap, and it's hard to complain about it. I do get annoyed with the notion that the audio soundtrack might be degraded in a rental -- that's a low blow. But let's not forget who spent time and money to create the content. We buy it and use it on their terms. If we don't like the terms, we don't buy/use it. If their terms get sufficiently restrictive, their business will fall and they will be compelled to change how they do things.
Anyway, I watched Jack Reacher rented from Redbox a couple of nights ago on a Samsung BDP-1500 (of 2009 vintage), while not connected to the internet. It went straight to the menu, and the audio options in it said that the soundtrack was a DTS Master Audio 7.1 track. I did not verify that this was the case, but that's what it said.
