Thanks for this!  Now, anyone have any idea what to use to burn the output folder to a DVD (make an AVCHD) on a Mac?
		
		
	 
Of course we have 

The simplest method, but not free is to use Toast 9 or 10 with the HD Module, but I guess, you're looking for a free solution 
So if you are not afraid of using the terminal you can do as follow, as Snow leopard gives you all the tools to do it !
Pre-requisite : you have chosen the AVCHD Disk option in TsMuxeRGUI (BluRay Disk option work too on Sony BDP-S300/550 but not PS3).
Now, we will supposes the following things :
- Your blu-ray structure is located in : /Users/My_user/My_blu_ray
 
- You want to give your blu-ray the name : MY_BLURAY_LABEL
 
- You want to put it in a single side DVD, so size will be  : 4478 (8140 for Double Layer)
 
So, now, let's play. Open a terminal box (applications --> Utilities --> Terminal)
1. Creation of an empty image :
	
	
	
		Code:
	
	
		dd if=/dev/zero of=$TMPDIR/bd_image.img bs=1048576 count=4478
	 
 2. Formating the image in UDF 2.5 and associating a volume name :
	
	
	
		Code:
	
	
		newfs_udf -r 2.5 $TMPDIR/bd_image.img -v MY_BLURAY_LABEL
	 
 3. Now we are mounting the newly created image
	
	
	
		Code:
	
	
		hdiutil mount -nobrowse $TMPDIR/bd_image.img
	 
 4. Copy of the blu-ray directories to the image
	
	
	
		Code:
	
	
		cp -Rv /Users/My_user/My_blu_ray/* /Volumes/MY_BLURAY_LABEL
	 
 5. Unmounting the image
	
	
	
		Code:
	
	
		hdiutil unmount /Volumes/MY_BLURAY_LABEL
	 
 5b. It seems that the volumes is unmounted but not completely detached
	
	
	
		Code:
	
	
		hdiutil detach /dev/$(diskutil list | grep MY_BLURAY_LABEL | awk '{ print $NF}')
	 
 6. Time to burn the DVD (the -noverifyburn option, if you don't want to very fy the DVD after burning)
	
	
	
		Code:
	
	
		hdiutil burn -noverifyburn $TMPDIR/bd_image.img
	 
 7. It's finish, so just a little cleaning to remove the temporary image
	
	
I hope, I was complete enough. Have fun.
This as been test on a Sony BDP-S300 and a BDP-S550 and PS3.
