Demux BBC HD TS correctly?

Anyone figured out a way yet?

I've just added H.264 demuxing to my command line tool, xport. I've tested it with a BBC stream, so it should work. It will start the demuxed H.264 video stream on an I-frame and align the audio to the first frame in that GOP.

It's still a work in progress, as some features (like video parameters, video bitrate and frame/field counts) that work in MPEG-2 are not yet available for H.264 (mostly because H.264 is such a PITA to parse). However, the basic demuxing is working.

I've been able to use MP4Box (with YAMB) to successfully de-mux some BBC clips....

the important part is that the demuxed stream starts with a keyframe and the demuxed audio is in sync with the demuxed video
