I have purchased only +R inkjet printables for the last 7 years or so. I've used exclusively NEC drives so far, and have flashed their firmware with code that has the Booktype permenantly set to DVD-ROM.
Basically this results in every DVD I burn looking like a retail DVD to other players, and I've had almost zero problems with older player compatability.
Note that doing this will probably void your warranty...but on a $40 drive it was worth the risk. Lots of info about hacked bitsetting firmware over on www.cdfreaks.com.
Here's another great utility from that site: http://dvdidentifier.cdfreaks.com - this tiny program will read a recordable DVD, tell you if it's a +R(W), -R(W) etc, what the booktype is, who made the media, and other tidbits of info.
