Both DVD and hard drive camcorders compress the stream a lot more aggressively in order to cram it into a relatively limited space. MiniDV will have higher overall quality, particularly when the camera or objects are moving fast.

A quick web search suggests that an 8cm DVD can store 1.4Gb, which for 30 mins recording time means a raw stream speed of about 6Mbit/sec. MiniDV uses the DV codec, which outputs data at about 25Mbit/sec.

A hard drive camcorder that supports DV would be near perfect - the least amount of compression but more than 80 mins recording time (assuming the HD is bigger than 17Gb)
