Samsung DVD-VR300 DVD Recorder/VCR Combo
Very touchy machine
I was able to play only one of five DVDs I made on this machine.  When recording from an attached video camera, everything looked fine, picture appeared on TV going through the DVD/VCR, Record light is nicely lit, after finishing the DVD it played well on the Samsung. But when trying to play back either on my Sony Vaio or my Apple iMac, all I get is a soundless black picture.  When I recorded on DVD-RW from a videotape inserted in the VCR, I could play the result on my Sony.  But the next tape I recorded only caused Microsoft to keep asking me to send an error report when I tried to play it on my Sony.  My Apple refused to recognize it as a DVD.  Unpredictably incompatible.  When I called the Samsung helpdesk they told me to call the computer manufacturer.  I guess I would have to call both Sony and Apple then?  Crutchfield was the seller for this product and they actually have a very helpful helpdesk -by the name of Darren-  According to him I should try a different brand DVD disc.  I tried Memorex instead of the Office Depot and found that this brand of disc solved the problem.  Question for Samsung: Why don't you have this on your troubleshooting page in the manual?  Why does the dealer know this, but you don't?
