I just bought a Sony HD handycam (HDR-SR10) w/40 GB HDD. The camcorder records in AVCHD format. However; Leopard on my computer doesn't seem to recognize it. I have to use Sony's PMB for Windows to import .mts files in the handycam to .m2ts on my computer. .m2ts files are too not supported my OS X or iMovie. Someone told me that the best way to get around this issue is to convert it into MPEG-2 stream and export it to a Mac, and it works fine. But, I am confused with this. I know AVCHD uses Mpeg-2 codec, but exporting to a mpeg stream will diminish the quality? I shoot videos in Full HD(1920X1080i) and dolby 5.1 but I feel kinda hosed not being able to reap the full benefits of HD.
