So I tested playback with other commercially recorded tapes. The Mary Poppins tapes appears very compatible with my VBT-200. However playing other tapes, there is a fair degree of variance. Some play well and others less so. The worst case was a Columbia House Tape from the early 1990s which displayed a noticable flag wave which in the worst case was noticable about 10% of the top of picture. Best case was a tape which displayed no flag waving at all.
