I'm surprised Sony doesn't provide a Burn-to-AVCHD function -- given they are one of the co-inventors of AVCHD.
After rendering what would seem to be a proper AVCHD .m2ts file (18Mbps VBR AVC with 5.1 or 2/0 AC3) -- is there a folder structure it must be placed in before burning to a DVD?
Is there a program that does this without recompression?
