I have a few purchased DVDs that will not play. Two have played one time. The message is "No Disk". Thanks. Suzanne

If this happens with various disks then the laser assembly has lost its ability to focus on the data on the disk. Time to go shopping since repair is not cost effective with those things.

some players will only play back DVD-R .. some only DVD+R .. many older ones wont play DVD rewritables at all...

DVD+ and - R recordings have lower contrast than purchased factory DVDs .. so if the laser in your mustek has a bit of dust then that will first effect computer written disks .. you can get a cleaning disk .. those have little brushes that brush off dust from the laser lens .. more likely though if your mustek is an older type, that you have to use DVDs that are compatable with it .. while DVD+R is the better format .. most older DVD players are compatable with DVD-R ... so thats kind of the standard that works in most players .. however there are a few exceptions .. most newer equip will play either, even rewritables ...

Sounds like the lens went out. If the dvds played fine b4 and lens cleaner doesn't help, it is most definitely the lens.

you need to select the disk as audio disk in the burning application, then select tracks and burn it.

you will need to get a drive that suports all the disc types you will be using

Hi

This is problem exactly with finalizing for finalizing after disk burning You need to press stop button and finalising menu will appear in your display at that time you need to press Record button top finalize it will take a little time for finalizing then your DVD will play fine in all DVD players

Thanks

well are the dvds that play in the video are original or burns if the burns do not play proprerly maybe they were not formatted properly

If other dvds play then try getting the same movie but from another supplier if it persists the check yo dvd if it uses a dvd ROM then replace it with anew one.
thanks

Did you try to clean lenses on laser head?

My Smasung DVD/VCR Combo stopped reading DVDs because of a dirty read head. It started by only playing disks sometimes, and progressed to never playing disks. I assumed it was a dirty laser lens so I bought a lens cleaner set. Unfortunately my player wouldn't play the cleaner disk.

So I took it apart and cleaned the laser lens manually with some isopropyl alcohol (the clenser that came with my cleaning disk), and a lens cloth (that came with my glasses). Just open the case (starting with the screws in the back) and remove the snap in cross panel that obscures the lens of the DVD portion. Put a drop of cleanser on the lens and gently wipe it with the cloth.

Oh and by the way, I take no responsibility if you break your own player while following my instructions. My own DVD player was far out of warranty at the time I cracked it open.
