"DVD+R, a recordable DVD format that along with its rival DVD-R, is 100% DVD compliant as specified by the DVD Consortium (a group comprised of the ten companies who originated the DVD format). "

While you are correct that the +R format isn't officially sanctioned, it is 100% compatable to the DVD standard.

There are several references to that fact online. The problem is that there is a flag that the player uses to identify the disc. The flags are "DVD-ROM", "DVD+R", and "DVD-R" as well as ones for the RW flavors. IF the player is old, or the manufacturer is being pissy/cheap the player may not allow (or understand) anything other than the DVD-ROM flag or may allow some but not all of them.

Again, as DVD-Rs are pressed with that designation at the factory, you're stuck if it doesn't work, however, with the plus (+) format you can tell the burner to "lie" and write "DVD-ROM" to the disc describer bit. That's why it's called bitsetting. At that point, it should work as the reflectivity of +R discs is 100% in line with the DVD consortium's standards.
