Concerning suggestion 2, I've voiced this opinion in several posts; I don't understand why CL would put any restriction on the "Create a Folder" size option. Not for DVD, AVCHD or BD, period. If smartfit is used in conjunction with "Create a Folder", then smartfit to the user specified media size. Yes compression is available for BD folders, just not in PD8, maybe in the future though if they think it's important enough to put on the PD development roadmap.
