Hi,

I'd like to edit my AVCHD footage to a AVCHD DVD using the following workflow...

1) Import my AVCHD clips into Sony Vegas (v8.0c) - 1920x1080 50i / 5.1 project.
2) Render the video as Cineform, audio as 5.1 (I'd like to render to AVCHD, but Vegas crashes).
3) Use Nero Vision to create a AVCHD DVD

However I'm failing miserably at stage 2. When I attempt to render the video as Cineform, it's impossible to set audio as 5.1 - either as compressed AC3 or uncompressed PCM. I can only set audio to stereo.

Anyone experienced this problem, or have a work around?
