Hook it directly up to the TV to see if it is producing a signal in the other modes.
Due to copyright issues or language, some makers exchange VTR for VCR etc...
I am trying to record from my Palmcorder onto a DVD using a Pioneer DVR which keeps telling me that there is no DV camcorder connected despite the fact that it is connected on the front panel. Under the recording instructions it says to "set the camcorder to VTR mode". I can't find a VTR mode option anywhere. Is this why the DVR is not recognizing my camcorder?
