Re: possible bug in version III release alpha 9.8

i don't know if you've solved this yet, but i would recommend trying a more
expensive CD-ROM drive and faster processor both. before you do so, though,
find out what the fastest you can get a clean rip is at the moment. though
short of 56x, it might be perfectly acceptable.

good luck,
aaron.
