I believe, I have had this problem also, or a similar one.

I've reproduced this problem not only with cdparanoia, but also
cdda2wav.  

Interestingly, the problem seems to be related to the KIND of music.
I have no trouble ripping various rock sorts of things, but *opera*
CDs universally bog near the end of the track while ripping.  I am not
sure why this happens, but have found that if I'm patient enough
(i.e., take an hour or two for a single CD), I get an ok rip.

I posted to ask about this problem earlier, but got no responses.

Best,
Robert
