SYMPTOMS
A Windows NT Workstation or Server computer with a Mitsumi CD-ROM exhibits
disruptions in video playback: images stop moving, sounds repeat or have
gaps. Files can still be read from the drive as normal.
CAUSE
The Mitsumi CD-ROM driver spends up to a third of a second at the DPC
level, where it has complete control of the computer and locks out all
other programs. This freezes video and fragments audio. When sounds clips
are playing and the hardware does not receive the data for the next part of
the clip, the system can neither complete nor stop the sound, so the drive
just repeats the last data it received.
STATUS
Microsoft is researching this problem and will post new information in the
Microsoft Knowledge Base as it becomes available.
The CD-ROM mentioned here is manufactured by Mitsumi, a vendor independent
of Microsoft; we make no warranty, implied or otherwise, regarding this
product's performance or reliability.
