Page 1 of DVD LG 8060 drive help needed

Have got an LG 8060B dvd rom drive however it only seems to read DVD-R and DVD-RW. There is a "no disc message" when I put a DVD+R or DVD+RW recorded disk in to it to play a movie etc.

Is this normal, is my DVD drive too old?

Would apprecite some help,

Cheers,

Bryce
