Many Thanks for that reply. It helps a lot.

I shall peruse that website of course.

The problem with sound is that if I input the guitar directly to the soundcard, I shall have to wear a headset, in order to hear the guitar and the accompaniament. I don't like using headsets, period! I shall also need a mixer unit. How the sound is synced with the video then, I have no idea.

So I am trying to use the amplifier as a monitor for the sound, whilst the rest comes from the 'speakers of my PC, recording into the webcam. To play the backing tracks from the PC, I use a Sony hi-fi set, with a 'game' facility, that inputs to my soundcard. I have never had any trouble with it before.) Again this goes directly into the webcam.

At present, the web cam is picking up the amplifier signal, which is fine, but also the actual sound from the guitar gets through and casues distortion. This was with Windows Moviemaker running the camera by the way.
Maybe I need a wireless mouse so I can sit further away!

I downloaded Logitech updates and now I can record indefinitely with the webcam, so this is much better. However, I am still getting interference on sound and vision when I play back the video. In some cases I discover that the soundtrack suddenly ceases altogether.

So it looks as if I should have either a new sound card, or enable the onboard audio setup. If that doesn't work, I will get a 'Bare-bones' bundle and upgrade to Dual Core and a SATA drive.

Many thanks for all your help. It really is appreciated.
Regards.
