So no. and secondly no work has been carried out to implement mpeg4 support for any of the chips yet anway. (well except for the h263 support, but that was a complete waste of time). If mpeg2 support is made to work then you should be able to get HD with no problems on the CX700 (the CN400 did 1920x1080i effortlessly). Also... fyi freesat HD is DVB-S2 which is actually mpeg2 - 1080i. you're thinking of FreeviewHD which will be H264. apparently.
