So, I did my first shoot with my brand-new DVX100A, using Panasonic PQ ("professional quality"... as opposed to what, amateur quality?) tape. I was surprised by the number of dropouts: 3-4 in a 30 minute shoot. That seems high. Should I be worried about the camera? Is Panasonic PQ tape of modest quality? Or is that normal (that seems unlikely)? Thanks in advance...
