I have a Sony TRV33E and a helmet cam that plugs into the AV-in socket. I also bought a remote control unit so that I can control the camcorder when it's tucked away in my back pack when recording on bike footage. Everything plugs in fine and I get sound and image from the helmet cam when viewed through the 'VCR' function on the Camcorder, problem is when I press either of the record buttons on the remote or the Cam it tries to record to the memory card and not the tape!! If I scroll through the on screen menu and press record through that it records to tape though Obviously the Std memory card fills up in about 1min so I then get an error message saying 'card full' and no recording starts. I've tried removing the card to see if it defaults to the tape, but I then get a 'no card' error message I've looked through the Instruction manual and scanned through the Cam menu functions but can't find any options that instruct it to record to tape by default. This is really P'ing me off as I've now had too many 'on bike' runs spoiled by lack of footage at the end. I'm off on holiday in a months time and need to get it sorted by then. Can anyone help Thanks in anticipation.
