Answer» Interplay recently re-released Planescape: Torment on one dvd. As soon as I heard of this I ordered a copy and here it is! The problem, however, is that when I attempt to play it on my dvd drive, it does not read. I know it is not the dvd because it will play on other dvd drives. Also, my dvd drive has played every single dvd I've ever put in it, inlcuding dvd pc games like bioshock. I have media playing software like VLC, Winamp, and Nero. I use Windows XP fully updated, SP3. My dvd drive is a NEC 3550A and it is updated to its latest firmware version. I suspect I am missing software, because I built my PC, however I have no clue as to what software I would need for recognizing pc dvd games. Any ideas?First step is to try another DVD player. Quote I know it is not the dvd because it will play on other dvd drives. Did you mean on other PCs? It could be any number of things. Right, it plays on dvd drives on other PCs.

IF ( you put another drive in your PC) AND (the DVD still do not play) THEN SAY "The OS has got something funny" ELSE SAY "The original drive is on the edge". END IF I have a hard time believing my OS would be biased towards this one dvd, when it has played every other dvd I have used. Do you think that this is a likely possibility?

You ignore the possibility that the drive is failing or deteriorating in some way, e.g. the read laser is declining in output and the disk in question is the first one which is sub optimal enough. To test this swap your DVD drive into 1 of the machines the DVD is seen on and see if it runs... If not...= bad drive.Quote from: Salmon Trout on February 05, 2010, 12:34:57 AM Error of logic: My drive has always worked OK, therefore it will always work OK.

The error of logic actually was: My drive works with all other dvds except the one in question, so the problem is not with my drive. Regardless I was still wrong because it was the drive, which I found out after trying the drive out on another computer as suggested. However I still do not understand why a deteriorating drive would not just stop reading dvds altogether, instead of only reading some dvds.

Because not all disks are exactly the same. There are variations due to to materials and manufacturing. There is a tolerance range. For EXAMPLE some disks will be slightly more reflective than others. Others will not be exactly flat or round and the HOLE may not be exactly central. Some pressed DVDs will have slightly deeper pits than others. As for burned disks, these brings in a whole lot more variations. The playback system is designed to be tolerant of such variations, between limits. The idea is, put briefly, that great precision in manufacturing CDs and DVDs is expensive, however low power lasers and smart servo electronics are cheap. Problems can occur and drives can get picky about disks if part of the playback system begins to perform below its best. A disk which was slightly on the good side of the limit can now be unreadable on the same drive. I used a weakening laser as an example but there are other things like dirty or misaligned lenses and ELECTRONIC or mechanical faults that can lead to this. Your drive might get worse.

Did you mean on other PCs?
It could be any number of things.

Right, it plays on dvd drives on other PCs. If it played on another dvd drive on my PC, there wouldn't be a problem.

So ...
IF ( you put another drive in your PC)
AND
(the DVD still do not play)
THEN
SAY "The OS has got something funny"
ELSE
SAY "The original drive is on the edge".
END IF
