No, seriously, does ANYBODY have any idea what format this was?  The closest I can come up with is Cartrivision, though the Quasar Great Time Machine sounds like a possibility as well (even if it’s more of a lever than a knob).  The thing is, there was actually a LOT of home video formats before VHS and Betamax, back before pre-recorded media was commonplace and these things were basically only meant for recording TV shows for later viewing. So really, there’s no telling WHAT kind of wild and wacky device this could have been.

Also, apologies to the guy who was asking about “that one format where you could only watch it once and couldn’t rewind” and we kept insisting it was probably DIVX Discs, even though he though it was a tape.  Turns out Cartrivision DEFINITELY had one-time-only, no-rewind tapes, so it was probably that.  Technology is hard.
