[Stephen Smith] “Sony shoots on DVcam”
That should be SOME Sony cameras not all by any means.
Howard,
There is no way of telling if a tape was shot SP vs LP. But with DV if some shoots LP there is a good chance it needs to be played back with that camera. Most of the time DV produces automatically switch to the right settle, do you have a way to force LP playback? But even that, if it was shoot in LP often times you cannot capture from a different camera.
Other issues, the heads on the record camera are bad, or just a little out of align. A deck maybe able to capture the tape vs your camera, they are built to a higher standard and can normally accommodate wider tolerances.
So other than trying a difference capture deck, the next thing would be to borrow the camera it was shoot on.
