DVD Plays on one iMac/Not another

[DHKaplan]

I've got 2 iMacs running 10.5.6.

I've created a DVD on a Sony RDR-VXD655 digital DVD/VHS recorder/player.

DVDs created on the Sony will play on one iMac and not the other. On the one it won't play on the recorded DVD shows up as a blank DVD. The problem iMac plays commercial DVDs just fine.

I've tried to see what video utilities I have on the iMac that works and transfer them to the one that doesn't, but no luck. The only thing I haven't installed is Final Cut Express.

Any suggestions?

Thanks... DHK

Are these newer model iMacs? Did you finalize the disc in your Sony to see if that helps?

Yes, the disk was finalized. The iMac that plays is June '07, and the iMac that doesn't is December '07.

Thanks...

I found that out of the 4 macs at home 3 have Matsushita drives, one has an Optiarc drive. Only the Optiarc won't play the DVD. I went to the local Apple store and they are going to replace the superdrive...
