I need some advice on this peculiar problem I encountered. I did a recording using the Terapin TX3300 CD Recorder on MP3 format at the default bitrate. The recorded CDR was played on a PC using Windows Media Player 6.4 running on Win95 OS. It could not be played. I then used another PC with a later version of Media Player ver 7, same result. After subsequent weeks later, the first PC that I used could play the same CDR even though no upgrades were done. Can anybody help.
