6. What is the "real" max bit rate, resolution, and frames per second that you support for all the different formats?
Xbox 360 does not specifically block video from playing based on a maximum bit rate, resolution, or frames per second. The maximums listed above for each codec are what we have tested for various video playback sources. Higher rated content will not be blocked, but playback may be less then optimal. Use higher bitrates at your own risk.
Now this I find very interesting. Why are they recommending a bitrate that is bellow half of what VC-1 playback via the HD DVD drive is supposedly capable of? They have added the disclaimer that higher bitrates won't be stopped from playing, but they may be less than optimum?
HD DVDs can have VC-1 encodes at up to 32Mbps and we expect that the software playback of those encodes on the 360 to be absolutely flawless. This possess the question now, is the 360 capable of playing back the video on HD DVD discs at its peak bandwidth? I would like to do some testing with some high bandwidth VC-1 encodes, because if the 360 is infact downgrading HD DVD playback to ensure smooth playback, then we've all had the wool pulled over our eyes.
