Oh man those first few generations of CD burners were rough. We had this old Pentium 2 that had so little memory you had to close everything but the burner software (Easy CD Creator or something, IIRC) otherwise the memory exhaustion would cause a buffer underrun and the disc would be ruined.
A few years later my mom finally let us get one with buffer underrun protection (and some multiplier on the write speed) so I could make mix CDs with music off Napster for my girlfriend and life was good.
