Mark,

Well! Thanks for the info! The real virtue of CD technology right now is the
storage volume, not the transfer rate or seek time. CD-I is really running up
against some bottlenecks on this, causing some grey hairs. Part of the problem
is CD technology, and the other part has been Philips Green Book spec, which
tried to specify that all titles be written to assume some incredibly long seek
time. Apparently, Philips wanted to antipate the creation of portable CD-I
devices that had slower mechanical performance. I understand that the Green
Book has since been slightly revised in that regard.

Still, even 130K per second is not bad -- and I know a couple of engineers that
are working with multimedia computers that have ways to smooth multimedia apps
over that hump. It DOES require DMA, SCSI, and caching.

Paul
