Panasonic DMR-EZ75V reads ''NO DISC'' for DVDs

One possible reason is the discs may be scratched, another is the DVD discs are not in the same region of your DVD driver. Try to backup your DVD discs with DVDAid first, and then play in the DVD driver, then there will be region-free plyback for all your DVDs.

God bless you

Perhaps you got dust in on the lens. Try blowing it out with compressed gas, and then try it again.

There maybe a problem with the optic lens (dirt) try to clean it very gently with cotton, also the motor plate that holds the cd/dvd is not holding it very well so it not rotates at proper speed try to clean the both sides where the hole of the cd/dvd is when it´s inserted, if you think that you migth not have skills for that don´t do it.

Hope it help

I mainly use my DVR to record TV shows on DVD-RAM discs (Panasonic brand or Maxell). I've had no problems with the DVD-RAM discs. However, today when I put a DVD-R disc in the recorder, I got an "Incompatible Disc" error message. I tried a second disc from the same set, and got the same message. I tried out some of the DVD-Rs that I recorded last year and I could read them. Tried a DVD-RAM. That was OK. So, I tried another DVD-R disc. That one is OK. I don't know if the problem is that these DVD-Rs are getting a little old (2 years??) or if the recorder is developing its own problems reading discs.

Dear FixYa Team,

Thanks for your inquiry re my problem.

Since I posted, I THINK I may have solved my problem. I unplugged the unit for an hour or so, plugged it in again, and it DID play a "commercial" DVD that I had tried earlier. I don't know if this is a permanent solution -- we'll see. If not, I'll take the next step in seeking some help.

Thanks again.

just try playin the lens cleaner disc....
