For example I use Zoom Player for watching MP4 video, and the MP4 download can be used to check HD playback of MP4 video.

Generally any part of the electronics used can possibly affect playback. Ideally you would want to calibrate each video source. If you watch video from both the PS3 and the computer then you would probably want to check the playback of each device. Some electronics, such as cable or satellite, may not offer test patterns, and in that case one way to handle things is to calibrate for a reference output like commented in #2664.
With the PS3 you could download the AVCHD and burn the image to DVD media. In that case I consider it safe to assume that Sony has made sure the different video types allowed for Blu-ray will all match. By using the AVCHD you would have a reference for Blu-ray playback on the PS3.
With computers things may not be as simple, depending on the software used. With Windows there are certain issues that can show up from different containers or video types, depending on the video drivers or playback software. I'm not familiar with Mac, VLC, or color profiles to really comment about any possible issues in using different containers or video types from the ones you would typically watch with the computer. It's possible that VLC may not exhibit the sorts of possible issues mentioned in the series of replies to smokarz (start at #2651), but putting the calibration video through the same modifications as other video you typically watch might be a more thorough check than simply using the MP4 download to check playback from the computer.

Typical video gray uses 16 luma for black and 235 for reference white, as shown in the patterns. Computers on the other hand commonly use 0 for black and 255 for white. Often computers "expand" the video so that it fits with the computer range. Usually 16 goes to 0, and 235 ends up as 255. It doesn't have to always work that way, and 20 could end up as 0 after the expansion. Generally any video expansion will be handled either by the computer's video drivers or the playback program. Since I don't use the operating system or VLC I cannot really comment on what items to adjust for either changing or avoiding expansion.
Another possibility is that the computer could be expanding so that 16 goes to 0 and the display might not show the entire computer range. Some displays have settings to choose between typical video and computer input ranges. My Sony labels the input range as either limited (video) or full (computer), but since I'm not familiar with the display I also cannot comment on your display settings. Some displays have been reported as unable to display the full computer range, but generally I would expect most recent displays to have a way to set brightness correctly for computer inputs.

I am also trying to find out if over HDMI it is possible for the macbook to output the correct values (not 0-255)

I installed blacklight to bring the display values up to where they should be, but even with brightness set to full (its 24 i believe) i cannot get bars 17-19 to flash on the brightness test. Not sure whats going on.
