Why won't some DVDs play in my computer's DVD drive?
I have a small collection of commercial movie DVDs. Most of them are from the U.S. market place and some are from Asia... ALL of these DVDs play in my Phillips DVD player that is connected to my TV.
But only some of these DVDs will play in my DVD player that is in my Dell Inspiron 531 computer with Windows 7 Ultimate.
This computer has a SAMSUNG HD161HJ SCSI DVD/CD Disk Drive.
Some of the DVDs that will play on my computer are from the U.S. market and some of them are from the Asian market, so I don't think that has anything to do with why some of these DVDs will not play on my computer. Some of the DVDs that won't play on this computer are from the U.S. market too.
The DVDs that play just fine in my Phillips DVD player on my TV that won't play on my computer don't even seem to wind up to play on my computer. The DVDs that will play on my computer wind up (you can hear the sound) in the DVD drive within about 20 seconds and they start playing automatically in the Windows Media Player... but I've allowed all the others that will not play to sit in the DVD disk drive for several minutes each in my tests and nothing at all happens... there is no wind up sound and nothing at all happens on the computer screen.
This does not seem to be a problem with the software driver for the disk drive since some of the DVDs will play.
None of these DVDs are warped and all of them are clean.
I've tried two or three times testing each of the DVDs that won't play, taking them out of the disk drive and putting them back in.
Does anyone have any suggestions?
