MCX and Spring '07 update for Xbox 360
The upcoming Spring update for Xbox 360 has a lot of new cool features, including support for H.264 and MPEG-4 Part 2. So this begs the questions of whether MCX will now be able to play back videos with this format. Unfortunately the answer is no. This is because MCX uses its own set of video codecs seperate from the Xbox 360 dashboard (so for those counting that would mean there are 2 WMV codecs running on the Xbox 360 -- one in MCX and one in the dashboard). Therefore in order for MCX to play back new types of content the MCX title would have to be updated to add these codecs. And any MCX update for the Xbox 360 would be released through Windows, not through Xbox Live.
