It's not at all stupid.

I assume that you're talking about music vids? The only problem is that the live performance will, almost certainly, be different to the recording.

A huge problem I've found is that old records tend to have scratches and hisses, which are as painful to listen to as the muddy sound on VHS.

Be a bit more specific and I'll try to see what I can suggest (I'm off at IBC over the next few days but will get back to you)
