fairly typical music CD's.
(Details sent in private response)

They have pops and some repeats (like a skipping CD)
on the rip.
paranoia reports V's and !'s.

I was running from svn to xiph.org.
I think i updated and re-tried yesterday morning, similar results.

I'm on debian, so it never occurred to me to get a redhat FC3 package.
I can try.

Similar results (one may have reported all zeros though...)
on both my ancient CD-ROM, and fairly new (but very cheap)
DVD-RW.

Wasn't there a command to probe the PCI/IDE bus and get some
sort of vendor code from the hardware?
If so...  I wouldn't mind being reminded, then I can positively
ID the hardware.

I have ripped other CD's from this drive.

I will be happy to send any output you want.
Just let me know if you have any extra flags you want (like -v...?)
Also let me know if I should get the latest FC3 RPM, or if
you have more updates since the release... perhaps we
could synch through xiph.org or was there a version at sourceforge?
