I got a D-r2 recorder at Costco ($225). My sony combo player SLV-D300P says it plays both +R/RW and -R/RW. I think I have done everything right and finalized disks. Have tried 3 diff media (including maxel Japan, Ritek, and memorex. all of them play fine on the Toshiba recorder and on my computer and a toshiba standalone player. Would really like to get this to play on the sony upstairs. Anyone else have problems with this recorder or is this a problem with the sony player?
