Dvd says no disc

The player is defective, this is the common symptom.

Are the discs copy's or originals if there copy's some systems will not read them, if there originals then clean disc on laser eye with a cleaner disc

I think local disc cannot read your DVD. Put quality disc into your DVD.

its lazer is either burned out or too dirty to read the information on the disc try putting a lazer head cleaner through it

try to clean the DVD-ROM with Cd cleaner also try to check if the DVD back is clear (not scratched)

Tru cleaning your lens,(pysically) give it a blow ,or similar

Either your lens of the dvd player is dirty or the dvd's you put in have no data on them

Check the specs on your dvd player. Not all players will read dvd-r discs. Some players will only read commercially produced dvds. Hope this helps & please take a moment to rate my answer. Thanks.

Take the Disc out and put it aside. You must clean the Laser Eye, and clean dust and other matter from inside your recorder. Clean Eye with rubbibg alcohol and q-tip. A regular CD/DVD cleaner disc will not work. After cleaning, reinsert your Disc and Finalize it.

are they bootleg dvd's? if not try getting a lense cleaner because wrong disc means it's reading your dvd's as .mov files which only play on quicktime in a computer. if it reads your cleaner as wrong disk too then get yourself a refund cuz it has a motherboard malfunction.
