SOURCE: DVD player recorder won't read or play any disc

This just worked for me. Don't know how long it will last though. I found it on this webpage
http://forum.ecoustics.com/bbs/messages/15118/130292.html

To do a reset:
On the remote control press the SETUP button,
Press the right key on the remote 3 times,
The Preference page will show up,
Press the down arrow five time to highlight
"default", hit right arrow to highlight "reset"
Press enter to reset. Turn off/on machine, etc.

SOURCE: Loading DVD-RW discs

My recorder has stopped accepting NEW DVD-RW discs and ejects them.
There is no problem loading DVD-R (new or recorded)or loading previous recorded DVD-RW, initializing and re-recording
I have tried several different DVD-RW makes. Puzzling??
