I've built a couple machines now. But for both of them, I can read from the dvd, but I can not write. My first machine has a LG GSA-H55N, the second one has a LG GH22NP20. Neither can burn DVD or DL dvd. In fact, they dont even show up in the system profiler. But when I put in a cd/dvd, it does show up.

I've seached, but most listed DVD burners are older that people suggest. My local computer store is usually pretty up to date and current on hardware. Any suggestions on a newer or late model drive that works?
