I am having problems with Quadra 840AV's running Quicktime 1.6.1 and the Apple CD-ROM
My problems started about 8 weeks ago when our first Quadra 840AV arrived. After I had
been using the machine for several days I noticed that it would hang when playing
quicktime movies. I tried a number of players (MoviePlayer, FusionRecorder, Premiere 2,
etc.) - they all would hang the machine randomly during movie playback.
After some determined hunting, I determined that if I took the Apple CD-ROM init
out of the extensions folder, my movies would play without any problems. In fact,
I took all the inits and control panels out at one point except Quicktime 1.6.1 and
the CD-ROM init, just to prove that it wasn't a problem caused by another piece of
software (it wasn't). This situation is quite repeatable: CD-ROM software active
at boot-up= movies hang; CD-ROM init removed at boot= movies play fine.
Our second 840AV arrived two weeks ago, and it exhibits the same behaviour, but more
so with the MoviePlayer than other players - it crashes very rarely (less than once
a week) when playing movies from other software. Again, if I remove the CD-ROM init
from the extensions folder, MoviePlayer works fine.
I even had the hard disks swapped between the two machines to determine if the problem
was hardware related. It doesn't seem to be - after the swap, the newer machine played
up as much as the older machine had been. This definitely seems to be a software problem.
Has anyone else experienced any similar problems? I can't believe that I can have
these problems from two out-of-the-box machines without anyone else seeing the same
BTW - The machines shipped with CD-ROM software version 4.0.2. I downloaded 4.0.5 from
AppleLink, but this made no difference (in fact, the INIT version in the 4.0.5 distribution
is still 4.0.2).
