Hmm, we watch a lot of movies in this household and my two brothers-in-law are avid movie buffs/traders, so quite a lot of blu-ray films go through the PS3 here. I can remember only one or two that imposed trailers, piracy warnings, or other undesired material before the movie. I've seen a lot more of that in DVDs, and on HD-DVD. Blu-ray seems by far the more customer friendly platform.

I also really like the quality, though having a background in film product/editing I admit to being a bit of a snob about such things.
