PMJI, I think I know what you heard. An SVHS deck that accepts a VHS-size
tape cassette can play back stuff recorded in either SVHS or VHS mode. But
some high-grade machines also (or instead) accept a compact cassette similar to
(but not identical, I think) 8 millimetre and record/play in SVHS mode from
that.
