I have seen so many people buy AVCHD camcorders only to discover that the Mac is a very limited platform for doing simple native editing and high def disk authoring. All of the very latest Macs and monitors, for example, have yet to incorporate HDCP, thus preventing commercial content from being shown entirely. I may sound like an Apple basher, but I will re-state here that I have had a total of 19 Macs, starting with the 'fat Mac 512K machine' in 1984 and, most recently an 8 core Mac Pro, and most everything in betwen, so I am a huge fan, but I sincerely feel that Apple has totally and entirely missed the market when it comes to high def, AVCHD, BluRay, and the like.
In his typical hubris, he denies the viability of the technology itself, saying that Apple does not consider it worthwhile.
Steve Jobs has publicly treated the HD / BluRay trend in a very dismissive manner, quite possibly due to the inability of Apple to reach a succesful DRM arrangement with the BluRay consortium.
Many other AVCHDs from 4 other (PC-based) authoring programs play on these same players, so I have serious reservations about these Roxio disks. The Toast 10 disks I have burned play on the Playstation 3, but do not play on either of my 2 set-top BluRay players, despite claiming to be AVCHD-compliant.
