Switched to command mode DVD1(I know...) book: you will be unable to operate this recorder. That's all they wrote. Can't undo. Nothing works-screen freeze. HELP???

Hi,
Since unit has been set on DVD1 remote mode so you need to set remote control itself on dvd1 mode to communicate with unit.
Press and hold Enter and 1 numeric key on remote control for 5 seconds, this will change remote control to dvd1 mode, now unit will accept remote control signal and you can operate it normally.
Thanks.

Try to reset the player :You can also try a hard reset: Unplug unit from AC mains and remove all cables from unit. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the unit and see if it works..if this fails then you need Restart the recorder Press down power switch for more than 10 seconds until Sony DVD appears this will set to default factory setting in the player.....

See the manual on page 22.
The solution is to reset your remote code to DVD1 (default is DVD3).

Press the ENTER button and NUMBER ONE button simultaneously for at least three seconds. Viola, control returns.

Indeed, I did the same thing.... I did find the answer in the manual!
Here's a copy of it (pg 23):

Set the command mode for the remote so it matches
the command mode for the recorder you set above.
1 Hold down ENTER
2 While holding down ENTER, enter the
command mode code number using the
number buttons.
Command Mode Code number
DVD1 number button 1
DVD2 number button 2
DVD3 number button 3
3 Hold down both the number buttons and
ENTER at the same time for more than 3
seconds.
4 Let up, press RETURN, all done!

Follow-up to the person who quoted from page 29 of the manual: Not sure if this will work w/the particular remote you have, but for the remote that ships w/RDR-VXD655 you can change the command mode in which it is operating by holding the Enter key on the remote and pressing the respective digit appearing in the LCD. In your case that means while holding the Enter key, press 1.

According to Sony, if you turn the power on and hold the Enter key and the #1 key down together for at least 3 seconds, everything will default back to factory settings.

Pretty easy, Recorder shows DVD1 in display..OK Slide COMMAND MODE Switch to DVD1 on remote Control. This switch is located in lowe part of remote control and has 3 settings.

It´s is easy to solve. Your DVD was seted to DVD1. Push enter button plus 1 no remote control.
Now you are able to commnad your DVD and go to System Menu and change to DVD3 again.
After it, don´t forget to backup your remoto control to DVD3. Push enter button plus 3

I did the same thing and lost all remote control to the recorder. Try holding ENTER & 3 in unison for as long as it takes (30 secs or more ) to view change on TV screen. This should get u back to system menu where u can change back to dvd 3 (default ) If doesn't work get a one for all remote and enter code 0533 which will get u in to the recorder command lines. PS enter & 3 worked 4 me.

Slide the bottom part of the remote control down. Switch the bottom right button to DVD 1. There might be a white sticker that covers it so remove the sticker first. Then hold down the "Enter" button and the "1" button down at the same time for a few seconds. That should make the remote work again.
