Computer will not play dvd or cd, but it does show the player in My Computer

windows 10?
post the model number of this player.
is the player connected to its power pack, plugged in?
try all USB ports? or is it using eSATA port, no port type stated.
USB, when plugged in does windows (is it windows) go BINGBONG
sound, telling you USB is not dead?
does it show up in device manager
does it show up in Disk manager?
last would be "This PC" local explorer working and see a disk there.
play what.
CD-DCA
Home burned, MP3 music on CD or DVD?
store bought DVD ,say starwars DVD real not a RIP.
always test with real CD/dVD first, not burned copies .
then last we check that DVD-R worrs or CD-r burned disks play.
what player are you using,? I use VLC , only.

There is a difference between a CD "music usually or data" and "DVD". Some players/computers only play CD's. Some are DVD/CD players/writers. Which is yours. If you have a CD player, it will never play a movie. Put in #1.a CD and try. If it works good. Then put in #2. a DVD it might not be a DVD player. Past that it would be a defective player. Get a lense cleaner disk at y computer/variety store". Insert it in your computer and run the program.lay a movie. If it is scratched or dirty. Clean and try again. No luck, You have a bad player of software issue. The Disk player can be slid out and replaced at any computer store. $59? Good Luck. John

Two things to check: First, look on the tray edge - does it say DVD and CD, or just CD? If it does not say DVD,it will not play them. The second thing is you may not have software to play a DVD. Usually Windows will use media player, assuming you have a dvd player. You can also open "my computer" and the drive will show up as a DVD or just CD.

Dear Sir,
Try to check the data cable of your dvd player.

Hi,it's obvious from your problem that the particular disc that cannot be viewed on your computer is of a formatt not supported by the windows XP.some DVDs are of low quality which can be viewed practically on any DVD player but as a result of their low quality and the sensitivity of the Windows they are not recognized by your computer. In as much as other DVDS play on your computer,it means there's no problem with your computer,but an unsupported disc formatt is been trying to be viewed and there's nothing you can do to view a DVD formatt not supported by your computer.please don't be bothered.
Thanks and take care

the DVD is bad, or your firmware is not up to date, you also have to have a DVD Decoder in order to watch DVD's on a computer

probably your dvd player's lens is dirty try to clean it using a dvd cleaner disc.

does this drive tray front show this?. step1, page 33 in your manual
shows this. this is first, never last. it is NOW.

try the vlcc player. even i had same issue it was because of codecs. see if it plays in vlcc player

Is it the DVD player/cd burner combo on your computer or simple CD player?
Or
Compatibility: Check if your DVD player on your computer is compatible of playing -r's CD or DVD?.
Check the make and model of your computer and go to the manufacturer's website and find out from there.
Or
You might have to talk to the manufacturer's support.
and if you are sure that the DVD player and its compatible of playing -r's DVDs then first of all check by playing any +r's DVD and see how they respond. If you are certain that it plays - and +rs etc then recheck your recording of DVD's.
Also try installing a good program software like Nero on the computer which will give you options of controlling, burning and playing DVD/CD on your computer.
Best of luck!
