Yes, I agree its Sony. Last year we bought a Sony HD hard drive video camera. To cut a long story short, the software supplied was for Windows. IMovie HD/QT/iDVD did not work becuase of Sony's proprietary format.
Sony offered a link in their instruction booklet for the Mac software for the camera (the same software they supply for Windows users), and guess, what - they wanted me to pay £55 for it!
No way was I paying Sony again after paying £££ for the camera, so downloaded visual hub, which cost me a tenner and does a lot more.
Why can they not just supply both formats! It's ridiculous. I know other Mac users who have sent these Sony cams back on principle.
