OK, but were you playing the same footage (same dv tape) with all 3 cameras?
cause what happenned to me, was a bad camcorder recorded bad audio on dv
tape, which carried over
to any camcorder i played that tape on.
So did you try capturing new material on new tape using another camera and
testing audiio drift on recorder?
Or are you just substituting equiptment using this same dv tape (which might
have the problem recorded on it).
Just an idea!

Good luck,
AnthonyR.
