I'm trying to follow 4eyes workflow for rendering to SONY AVCHD as described in "RE:Nero gets BDMV authoring certification" and when I set the System setting to .m2ts as advised I get the message "cannot render to .m2ts as a compatable videon codex is not found".

What is happening here? I'm running the V8 and DVDA4.5 Trials.
