I have just got back some HDV footage from a shoot and have been told that the sound engineer who was recording with a Free Run Time Code, sent back an LTC onto audio track one.
When I capture the footage, audio one is just full of fuzz.
If I want to sync the audio to the video I need to get to this Time Code, how is this possible?
I have tried capturing with LTC as the source Time Code but this doesn't change anything.
I have been using a Sony HVR-M15 to capture. Is there anything in the set-up of the HVR that needs changing for me to get the TC?
Having read a few things here and there, am I right in thinking I need a scope with an RS 422 so that this workflow will work?
Any help is more than welcome, please correct me if any of my assumptions seem wrong.

This is very common in concert footage.
that fuzz is what timecode sounds like as an audio signal - kinda like a fax machine.
you need to bridge the output signal from Audio One to the LTC reader on your input device. If your capture device does not support LTC you will need to use something that does understand LTC.
your best bet is to do a deck to deck conversion to a higher quality format than HDV and use the LTC input on the receiving deck to accept the LTC signal via BNC or RCA out of Audio one on the HDV deck.

the audio people gave the timecode to you to sync insert the recorded audio from them under the video on the tape in post. what has gone wrong is that it was free running. SMPTEtimecode has a relation with video (every timecode frame is a videoframe) if the generator was really freerunning it is useless. the timecode can now change from 10:00:00:01 to 10:00:00:02 in the middle of a frame. which is wrong.
in a long concert say 3hours you can be confronted with the fact that the audio from them is perfectly sync on the first song but completly async on the last.
i hope you have time/budget to fix cause this can be very time consuming.
