I’m not surprised that the quality isn’t as good as that of a less expensive DV camcorder, but it shouldn’t be as bad as you describe! Was it all in “auto” mode? If the shutter speed was manually selected at a low speed, for example, that would explain the issues with movement… or if the “night alive” mode was left on (this mode drops shutter speed to 1/2 of a a second, so any movement will be blurred.
Here is a link to an objective review of the MG70, which is similar in spec (these guys haven’t reviewed the 77)

They conclude that JVC still have a long way to go to get the quality to miniDV standards… but it isn’t as awful as you have described.
My guess is either it is faulty or there was some issue with the settings.
Hopefully some JVC HDD cam owners can reply with their experiences.
