3 days ago I bought the Panasonic PV-DV53 Mini DV camcorder from Walmart for $348. I like the camera and all of the features, but tonight, I wanted to see what I had recorded so far (about 4 minutes into a Mini DV tape), and when I played it back, the picture has tons of graphical glitches, sound drops and big pixels showing up randomly. It is a Panasonic 60 minute tape. I was recording in LP mode. I watched what I recorded yesterday with no problems at all. Could it be the cassette or the camera? Should I take the camera back to Walmart? Get the same one or a different model? Also... I noticed that Mini DV tapes are the most expensive compared to all of the formats. How does Digtal 8 compare in picture quality and price?
