In short, I checked out a DVD from the library yesterday...it had full circle scratches...nearly looked like a vinyl record on the back plus a few smudges...my iMac accepted the DVD & it loaded.
I bought a new DVD set (an old mini-series from the 80s) 3 weeks ago...brand new, no smudges, etc & every time my iMac 27 inch screen took the DVD, it would have a sound like it's trying to find something, the it'll pop out. I tried it on my cheap dvd player near my tv & worked fine. Still can't get it to accept the DVD & load it into the iMac
So, my question is...why would a dirty dvd that has scratch lines around a dvd like a vinyl record accept and load the dvd fine but would spit out a clean dvd after a few weird noises then ejects on its own?
