When setting up a new project in DVD arch studio 5 - and setting the Disc format to "Blu-ray Disc" what Project Video Format do I select to produce a AVCHD Disc ?? Input rendered files are "m2v" & "w64" frorm VMStudio.
If you go to the File menu and open Properties, you'll see that Video Format is, by default, set to MPEG2. Click on it and you'll find the option to create AVC.
BTW, for optimal performance in DVD Architect, the best format to output from Vegas Movie Studio for a BluRay disc is the 1920x1080 MPEG2.
While it is possible to burn "AVCHD" files to a standard DVD using DVDA the disc produced is not quite the same as an AVCHD disc produced by a video camera. Such a disc may or may not play in your Blu-ray player. Not all Blu-ray players will play AVCHD discs in any case; make sure that the manual or box of your player explicitly says that it will play AVCHD discs.
I have several programs that will make AVCHD discs that will play directly on my Blu-ray player (actually recorder), but the discs made by DVDA won't play unless I first patch them using a program called AVCHD Patcher.
