Hey folks- I found you all through Googling about this particular conundrum:
I have previously managed to do this with the rather sketchy help of my manual and now cannot replicate it for love nor money:
(This is me:

)
Have old analogue Sony Hi8 camera. Need to get THAT into the Macintosh (iMovie is a doddle!). Connected it up to the Canon MV500i using the 3 jack from the Sony to the single AV on Canon and used DV out on Canon to Firewire on Mac.
Turned Canon to Menu/AV>DV ON and then removed tape from Canon as requested by manual.
Mac SEES Canon but tells me it has no tape.
Canon SEES/plays back Sony's footage...
Just the point of DV in to DV out seems to be sticking...
Even used the remote as instructed for RECORDING analogue and THAT didn't work either. (edited to add clarification- TRIED to use remote as for recording. Recording itself STILL works fine)
Anyone able to shed light on this now rather dated but still dinky video camera?
Pwease?
Thanks
PS: Did extensive searching here for answers BEFORE posting- found loads of interesting answers to other questions but none to this.
