At least with High Definition material. So far, all of the movies on Blu-ray are presented in their Original Aspect Ratio (sometimes referred to as OAR). The format is based on a total resolution of 1920x1080 pixels.

The reason that DVDs used anamorphic squeezing was to increase the resolution when a movie's aspect ratio was wider than 4:3. The DVD format itself is based on the 4:3 format (this works out to 720x480 pixels) and if no anamorphic squeezing is used, then you get the same resolution as laserdisc when a widescreen movie is encoded (the black bars at the top and bottom are actually counted as lines of resolution when doing it this way). By squeezing the wider aspect ratio so that it then fits in the 4:3 "window" of the DVD format, you then use all of the format's available resolution. When the movie is unsqueezed on a 16x9 display, it then has about 30% more resolution than what you would get had you not squeezed it at encoding.

Currently the PS3 is the fastest responding Blu-ray player: it uses the latest Blu-ray drive mechanism. The slower response of your player and the Pioneer unit that it is based on is directly related to the older Pioneer Blu-ray drive mechanism used to read the discs.
