Thanks so much for your advice Fellas.
Yes Michael that’s how it was, sorry if I wasn’t clear. I’ve just been crunching through a self-train manual. I hadn’t realised that setting a loop point seems to deactivate your menu buttons until after the first play through. Deleting it seems to have solved my problem. I was trying to have my audio and video looping at different rates but I’ve given up on this. And Chris, what you advise makes sense, so I’ll test that out as well. So great to be able to ask questions here.
Thanks again Sal
