My stuff is currently in disarray. So I don't have any samples, and probably won't locate that for several months. Remember, I'm just now getting back online, in a new state, after almost 8 months.
The colors are simply blurred more as DV. The end. It's not bad, no, but you can never really do anything with it again -- created DVD (yet again convert colorspace!), restoration, etc. It's fine to view on a monitor or TV (media player, like the WDTV or Samsung Blu-ray players). After it turns to DV, it gets worse the more you touch it. That's why
Huffyuv and other lossless exist. It's why Apple ProRes exists. People want (pro especially!) formats that don't degrade at every turn.
As you've seen, hardware plays a role in DV, too, since it was never agreed upon by TPTB. Each company is different. Again, unlike lossless.
The decode and encode codecs also vary highly.
And it really depends on the source -- how good is it, what was it's editing history, etc. You need to view such video at about 4x -- the size of a small TV -- to see the differences. It's not noticeable at a computer 720x480, which is tiny. (Few inches by few inches.)
