I have about 600 favorite MP3s - I use Nero 10 to burn them to a DVD, then I play them in a DVD player connected to an amplifier in my workshop. Only about 50 of them play. The rest are on the DVD and play fine in Winamp.
You might think it is a DVD player problem, but when I burned them with Cheetah they all played on that DVD player. I can't use Cheetah any more because I changed to Win7, and Cheetah does not run under W7. I wrote Nero, but they just blew smoke, and did not even answer my response email. Any suggestions would be appreciated.
