The biggest problem I seem to have is with video files. There seems to be dozens of codecs they get compressed with.
I do dissagree with the idea that CDs tapes or any other little bit of plastic is better than listening to a digital file. As he said, it is just a matter of compression and thus file size. A WAV is CD quality sound. My old tin ear can't tell the difference between a WAV and a 128kb MP3 file, a tenth the size. Unless you are listening in a sound conditioned room on about $10,000 worth of equipment you can't either.
I haven't actually used CDs or tapes for anything but "ripping" since the turn of the century. I have 4 MP3 players (2 cars, the house and the pool bar). All are DOS based P166 PCs running MPXPLAY.
