V1 AV lead..??

[SIMON40]

A rather frustrated friend of mine cannot playback video's taken with the V1 on his Windows computer. I suspect his system might not be up to speed- despite his other camera's playing ball...!
However- throwing in the towel,he reached for the AV cable to view via his TV- only to find the lead only has one has one channel for audio...!!!
I wonder if the audio output is one channel of the recording or a Mono output...?
Can anyone shed any light on this- and is a stereo lead available- as I cannot seem to find one..!!

Now I know why I stick to VGA/MP4.....!
