I have a Pioneer drive (which ship in the Sony Vaio desktops, funnily enough, and the Apple G4/G5s). It burns DVD-R and DVD-RW, and I love it.
Earlier this year I made a batch of 30 three-disc sets (90 discs total) that were packed to the brim with shorts (about 2 hours worth) and sent them all over North America. The people had a mix of old and new DVD players. There weren't any problems, except for one that had a spec of dust on it before I burned it (which didn't screw up the whole disc, just made one small part hang). Out of 90 discs shipped, I only ended up with one coaster, and it was my fault, not the drive's.
It is still region encoded though, which means it will only play in Canada and the US. You are allowed to change the region 5 times before the firmware of the drive locks it forever.
Just a note: I had to burn these myself because it was such a strange sized run (30x3). For future projects, if I forsee a run of a couple hundred discs I will have it professionally done (on DVD, not DVD-R). It's relatively cheap, and all you have to do is send out a DVD-R to the reproduction company. The addition of professional printing and on-disc graphics make it a "real" product, and it will be more durable and reliable in the long run.
