Oh, Will the six hour mode work OK without really noticing what this extra
error will bring? I suppose the one thing is it will convert the audio in
to a video signal so that all VCR's will record it. I kind of like the idea
of having track markers, but how that really can be implemented, I'm not
sure, but the four track cassette players usually have tones audible in
rewind/fastforward modes that may be able to be counted automatically, if
something supported that.

Hence auto-locators and time code on pro decks.
