Hi, Does anybody knows which DVD+R DL media works on the Intel iMac with Matshita DVD-R UJ-846 drive? I've searched the web, but I couldn't find a list of recommended media. Most DVD drive manufacturers provide a list, but Apple/Matshita/Panasonic don't...or at least I couldn't find it. In my experience, I've had a lot of trouble with certain brands and I don't like the built-in superdrive at all. Has anyone successfully writen DVD+R DL on the iMac? if so, which brands?
