I have the same problem after todays shoots. The playback is all jumpy and the time code doesn’t flow. I shot some material afterwards on a different miniDV cassette, at that wasn’t all that bad. Should I be honest to myself and say this jumpy material is beyond repair and I should just shoot it all over again. I´m not sure if this is just a bad cassette problems. I used cleaning cassette three times. Please tell what happened to you, or if you could help me out with a solution.
