The biggest problem I found with DV capture is that is uses 4:1:1 chroma subsampling which really reduces the picture quality.

In 4:1:1 chroma subsampling, the horizontal color resolution is quartered to reduce the bandwidth by half. In 4:2:2 chroma subsampling the two chroma components are sampled at half the sample rate of luma: the horizontal chroma resolution is halved. This reduces the bandwidth of an uncompressed video signal by one-third with little to no visual difference.

You are completely right about 4:1:1, but you might have missed one important detail. The ISD is PAL and I’m capturing in PAL and in PAL the chroma subsampling is 4:2:0, not 4:1:1, which looks light years better.

Oh, I didn’t know that it was 4:2:0 in PAL. That should look much better 😃 Carry on!

The whole existance of NTSC was the biggest mistake in history of television. Always problems…

I’d rather deal with whatever problems NTSC has than ever listen to the pitchy sped-up mess of PAL.
