Just thought I'd try and save someone else the frustration I went through trying to get Memorex brand DVD-Rs to work in my 17" iMac's SuperDrive. They won't even read never-mind burn. The Superdrive just whines and spins the disc for 2 minutes before ejecting it. In a word this sucks. I can (of course) use Apple branded DVD-Rs fine, but my set top player cannot read them (ARRGH!) Any recommendations for DVD-R media that works with BOTH the iMac Superdrive and set top DVD players?
