Ken - the TRV 110, 120, 310, 320, 510, 520 are all Digital8 camcorders that use Hi8 (or video8) tape.
It is misleading to others looking for answers tgo describe them as Hi8 machines.
I used to own TR3300 and V6000 Hi8, still own a TRV310 and TRV120 digital8 as well as a TRV900 miniDV camcorders.
There is a real and necessary distinction between the Hi8 camcorders with S-video, Composite video and stereo audio outputs, and the digital8 units with a DV socket as well as the analog connections. The TRV120 was especially useful for digitising material recorded on the Hi8 units - but there was an audio synch problem with longer clips.
