Don't forget that +R's need to be finalized, altho most writing programs do that as a matter of fact (except my 3 liteon standalone recorders) anyways. I use +R/RW's almost exclusively in all my recorders. 3 Standalone Liteon, a Plextor 755SA, an LG CCW-h20L (which relaced a good Samsung writer). Have not had a single problem with computer generated DVDs playing in several DVD players (Sony Blu-ray, Lite-on, Cheap Desay, and old sony, and several others.
(1) I always burn a DVD at no more than 8 X (I've burned several at 12X and 16X and they have played fine).
(2) I never by media made in china or India. Use to buy by made in Japan but can not find so I now buy made in taiwan. Never Buy off the wall brand, and only stock up when on sale.
(3) I always do a quality scan of a DVD movie to check the media/lot (batch). I use plextools and nero for the scan check. (there was a registry change to allow Nero to use samsung drive. Have not tried to do a quality check using the LG H2OL drive.
