Yes...from other correspondence, it does seem my computer system has a lot to
do with it...as one would expect from a device that uses near 100% of CPU
I have found a further problem...the TEAC will NOT read multisession disks -
it reads only the first session.
I am taking the TEAC back tommorrow...
The toshiba quad scsi is wonderful
Mitsumi...has some quirky read problems, makes noise (eeek! eeek!) during
access...is ok for the money..but the inability to read Cinemania 95 sends up
a red flag..
TEAC -- not capable of multisession, high cpu use, etc. etc. as reported
here... avoid it.
