My CD-R discs all corrupted by freebsd.

Try setting the write speed to 24X, or something else lower than the maximum. Use the configuration file in /usr/local/etc/ so this doesn't have to be set on the command line each time.

When I lowered the speed from the maximum, cd's burned correctly.

You mean your cd's incorrectly burns with more speeds?

I'm not played with speed yet.

I'm not played with speed yet.

When I burned CD's at maximum speed, my CD's didn't burn correctly. My CD's burned incorrectly when it was at the default of higher speeds. When I lowered the speed to 24X, maybe 32X, not sure, it burned correctly.

Try any lower speed, then raise it to the maximum where it burns correctly. 24X speed isn't that slow. Try it.
