I have a SONY camcorder, HD but not 3D so can't experiment with this for you, however looking thru the help files of the Sony PC software (PMB), what you want to do should work.
Sony & Panasonic developed the AVCHD 3D format together.
According to this you should have no problems unless you are trying to use DVD media instead of BD.
Have you tried Panasonic online support?
