Bought a set of audio CD’s (WAV, not home copies) from an education company–it’s academic lectures. Only some of them play in my Matshita UJ-850S (Firmware 1.20?) (in a Dell XPS Gen 2.)
But all of the cd’s play on my old thinkpad’s Toshiba DVD-ROM SD-C2302.
Any reason why not? I put the Cd’s in, and the computer simply reads them as not having any disc in.
