DVD+R DL wont work in my JVC DVD/VHS RECORDER

SOURCE: JVC DR-M100S

try recording on a re-writeable dvd i had exactly the same problem on a dr-m100 (the more primitive version of the dr-m100s) as follows: -- heard a distinct pop while recording -- after that, an error message indicating that i am trying to record on a write protected disk, even though i am not. recording on standard blank dvd now impossible. -- unit still plays dvd normally, except it takes twice as long to find beginning of program -- wierdly, it still records on re-writeable dvd's. the re-writeable dvd must be formatted correctly. the unit still formats re-writeable dvds normally

Had the same problem on my JVC vcr/dvd combo unit.
You need to turn off the timer function. I did this by making sure my remote was in the "VHS" mode...turn the swith from TV to the right (found on the remote in the upper left corner...an then hit the "vcr" button. Then point the remote at the VCR unit and hit the No. 4 button (timer turns off). Your unit should not have the red timer displayed and you should be able to play your tapes okay.

Hope this helps.

The disk must be finalized. Instructions are on page 79 of the instruction booklet for the MV5S. I can't get the manual to download from the MVC site, but maybe it will work later. Hopefully you have the manual.
