One thing is that on the Mac Apple natively supports the Panasonic DVCPro and DVCProHD codecs. This might give them a leg up handling colorspace issues. I don’t have an answer to your problem, except to say that since the US is a 7.5 IRE black and most DV and HD signals are 0 IRE Black, we will continue to have color space issues affecting blacks, and depending on the OS version, platform, QT version, video card or other factors, we will struggle trying to make our ins and outs match.
In this digital age, which is sold to consumers as the promised land, there are as many potholes as NTSC. Actually, in some ways the simplicity of analog will be missed.
I sort of miss it already…
