DVD doesn't mount, but writing works fine.

I am able to read the CDROM drive about 25% of the time. Very
frustrating. There have been CDROM access issues in Fedora since FC2.
It is about time this got fixed.
I tried adding "hdc=ide-scsi" to the kernel boot line in grub.conf.
That makes the device /dev/scd0 rather that /media/cdrecorder. I now
can't access a CDROM without trying 8 times.
