Samsung DVD-VR300 DVD Recorder/VCR Combo
Lots of write failures
This DVD recorder seems to use cheap parts that result in a large % of disc-burnin failures.  Even though DVD-R is cheap these days (but not so with DVD-RAM), you'll be much better off and happier with DVD recorders from Panasonic.  (The Panasonic DVD recorder/VCR combo is also $200 cheaper!)
