It would be very interesting to view exactly what MHEG data is being
transmitted.  Luckily Myth actually records the MHEG data stream in a
standard mpg recording.  So if you could record 2-3 minutes of BBC1,
without any transcoding, and upload it somewhere and post me a link then
I'll see if I can see anything different.
