My recording of a collected song runs to 82Mbytes poor qality AVI for 3 minutes. Even MP2 won't get that down much and still look good - but we are moving in the right direction. I am putting it on CD and have a CD resident MAcrobat which apparently works on a Mac. The PC version works a treat. And I still have 400 Mbytes left on the CD. A more user friendly medium at present, I submit.
