VC-1 in M2TS playback possible?

[cncb]

I have some M2TS files with VC-1 video and AC3 audio. When I attempt to play them back on the XBOX 360 through WMC I get a blank screen with the audio playing in the background. I can pay these fine on my PC in JRiver MC, however, WMC and WMP also don't display any video. Any ideas how I can get video on the XBOX or is it not possible? Thanks.
