Yes thats a real shortcoming of the Sony camera.

To work around that, I had been thinking about using one of the more  
sophisticated blackmagic cards, say Decklink Studio or Extreme which  
takes in HD in whatever format (SDI, HDMI, DVI, YUV) and at the same  
time provides a downconverted version at its output. If you then run  
that output into a normal capture card, you should be able to stream  
HD and PAL/NTSC simultaneously. I haven't actually tried it but seems  
good in theory ...
