Something has to be the cause, but it could be several things. RW discs are supposed to be rewritten many times over, research suggests even hundreds if not 1000 times. In reality, i doubt you will get 1000 rewrites, but should be able to get way more than 6-10.

I would suspect it is one of the following things:
-Discs are old or defective, RW discs don't last forever and can become compromised from heat, age, etc... or could be a bad batch
-Discs are getting scratched - many people will stack up the discs, this scratches them up pretty bad, always put them back into a single case to avoid scratches, even finger prints can get on the surface and effect reading or writing. Make sure they're scratch free and clean.. if you do have to clean the surface, always wipe away from the center straight to the ouside, not in circles (data is stored in circles around like a record, circular scratches take out huge chunks of data)...
-Your dvd reader/writer may be malfunctioning or failing. All dvd players and writers use lasers to read and write data, they usually don't last forever.. the read or write laser could be going bad, resulting in bad playback or weak data writing, or maybe even over powered data writing causing the disc material to get damaged more permanently.

if your issue is the dvd player itself, the only way to know would be to check out some completely different discs (brand new) and see how they work out, or try using your current discs on a computer burner or something else and determining if its just bad media.
of course, if the discs are scratch free and totally clean and good looking, and you have issues on several brands, types, ages, then suspect your dvd player/burner going bad..

hopefully this helps somewhat, let me know if you have further questions or more info. thanks

    Thank You Electronic.

    Based on your reply it appears that it is the DVD recorder/player that is the problem.

    Can this problem be fixed by a DVD repairer?

    Well it could be repaired but would likely need a new laser, the most expensive part of the unit. Most of these just don't last forever and have a finite lifespan. Unless it was very pricey or has some sentimental value, I would probably replace the unit or just use it as a dvd player or cd player (those lasers are probably still newer, not as worn out). Best of luck

Thanks for using FixYa. It seems that the lens is unable to read discs. To start with try running a lens cleaning disc, if that does not work then you have to open the unit and clean the lens with a Q-tip dipped in alcohol. If still the issue is not resolved then the lens should be replaced however, replacing a lens will cost you around $75 and a new one will cost you around $50. Please do accept the solution if the issue is resolved or post a comment for further assistance.

    The DVD discs in question appear to be corrupted as they don'k work on other players.

    Are you confident that the use of a laser cleaner and lens cleaning will solve the problem.

    Can the corrupted discs be cleansed?

DVD will not recognise discs

I think that moisture has formed on the boards.

The best thing to do is to take the recorder
and put in a warm room,connect it and leave for 2-3 hours.
Then try with a disc again.

I hope i`ve helped!

Recording Fall, Invalid disk

Try using Sony +R discs. or +RW's are good, any brand as long as they are +'s. For some reason alot of +R discs brands will not work, I wait and just get Sony +R or the +RW's on sale and stock up and I have no more troubles. Mine is the 05MU. The ZU is a little strange with the RW but will still record. Hope this helps.

LiteOn LVC - 9016G dvd recorder Problem.

throw it in the trash- I got 1 from costco, liked it so much, bought another a week later. First one started giving me the "invalid" msg, 2nd one did the same 1 wk later, so I guess they're programmed to do so after so many hours after being plugged in. Too bad, cuz it was the easiest to use of 5 previous models I tried. Their easyguide onscreen menu was the greatest, plus the status of time, pause & recording indicator, which you could turn on or off as needed, were very useful.
A real shame to have to throw in the trash. Won't ever buy another thing from them.
