The HDV camera was a Sony HC1. Despite the small size and single CMOS imager, the artifacting in busy contrasty scenes was not problematic of the sensor, but the compression system.
We've seen the same moire effects and definition problems with movement on Sony Z1's and A1's. I can't speak for the larger JVC and Canon HDV cameras but I defy anyone not to notice compression problems on scenes with reasonable levels of movement, detail and contrast; and in shooting outdoors in Australasia, we have lots of those issues.
There are going to be better (compressed) formats in the not too distant future that will put pressure on the the survival of HDV. And for broadcast work and large 50" & 65" plus plasma presentation displays like we do, I'm sorry but despite those static, perfect conditions we shoot in all too rarely, HDV just doesn't cut it. Sorry. For other areas of video production, people seem as happy as Larry with HDV.
