I have a Samsung DVD V9800. Already recorded DVDs and VCRs play just fine, but I cannot seem to get the VCR to record. I can set the machine up to record at a certain time, then set the TV to the channel I want to record (which is in a different input screen from the one I set up to record on). I record only a blank screen. If I just press "record" while in the channel I want to record, I still get only a blank screen on playback. Can you help, please?

Did you finalize the disk? If not, this should solve your problem. When the disk is finalized you should be able to play it on your computer if you can play other DVDs on it. Some other DVD players can only play specific disks (i.e. DVD-R, DVD+R). This may be another problem.

Storms tend to fry most delicate electronics. Quality surge protection is required.

if there are rca ports on the front of the vcr which are output, connect those to the tv input 3, the input to input connection is definitely not going to work...

Hi,

Have you finalised the disc before trying to play it elsewhere? If not this could well be the problem. The option is the menu.

Hope this helps

To be able to select AV1, you have to first go into the setup menu and set the control set top box setting to OFF. I think you go to the menu >> setup >> features >> set top box control >> select OFF. Note that this has the side effect of erasing any previously stored timer settings.
