811S problems

OK, I recently installed a new 811S, and for some reason it will burn dvd’s but not cd’s. When I tried to burn a cd using nero, I get an error message saying it’s the wrong media, and it asks me to insert a dvd. I also have veritas record now, and it does not even recognize the 811. The drive is installed as the master with a plain old cd-rom as the slave, and I’m using HSOP firmware if that makes a difference. Any help for my pathetic newbie question is greatly appreciated.
