I normally make reduced versions of our dv video projects as an archive for
our school and then burn the .mov files to a cd using nero 6 and win xp pro
on several computers.
everything seems to go okay during the burning process, and the original
files are fine, but the burned cds are very temperamental to read. often a
cd drive wont recognize the cd or the files will show in the directory but
not play in quicktime.
this has happened on several cds and the problem persists if the cds are put
in different computers. some computers are a bit more successful than others
trying to read or play the same cd.
can anyone please advise on what might be going wrong? thanks for any
advice.

QT imposes a heavy burden on the processor, so another format may be a
better choice - depending on your unnamed platform and unidentified
software.

Try writing one balky MOV to the hard drive and play it from there. If
that's clean, then the problem is the quality of your write to the CD
and the speed of read from it. Check that quality with CD/DVD
Diagnostic, CDSpeed or your choose of *measurement* tool and see if you
can find a better match of medium, write speed and writer.

First, I have to question why you are using MOV? You're certainly not on a
Mac, so why not use something way better than MOV? For 700MB of space, you
can easily fit 90 minutes of video in Xvid or Divx. If you are doing
low-res (352x240), you should be able to get 3 hours out of a disc.

So, you are claiming that the disc you have just recently burned is not
being read back by other CD drives. How well does it playback on the burner?
Check it for errors, its the C2 errors that are going to cause problems.
Nero's own CD-DVD Speed software will report back C2 errors. Don't believe
it if it says "error free," though, you will have thousands of C1 errors
that are just going to be corrected during reading. That is not to say that
C1 errors are causing your problems! If you have C2 errors, thats your
problem!!

Then, since you have only 3 components that could be causing problems, CD-RW
drive, CD-R disc, and CD-ROM drive, you could then try different media.

How are you burning the discs? You're choosing CD-ROM (ISO), correct, not
using any other stupid method (ie UDF).

Finally, can you try just copying the MOV file over to the hard drive and
then have the PC with the read troubles play it off the hard drive?
