I have got a Archos AV 500 PVR. I use it to record programs off my Sky Digital satellite box. However, I do not use a direct connection to record programs. Instead, my Sky box is connected to my old VCR (basically the inputs and outputs don't work for Archos and Sky) and so when I record a program it only records the left audio, and so everything only plays through the left headphone. It isn't anything to with the headphones, I've checked, and when I upload videos to my computer the sound only plays through the left speaker. It's because the VCR only records left audio.
Please can you tell me a way in which I can convert my video from left audio to Monaural?
