712A lead-in problem (drive pause in lead-in phase)

My Plextor 712A sometimes pauses at the initial of the burning. Detail: the light blinks orange for about 10-15 seconds then it stays green, at that time, all I can do it to restart the computer, then try another burn. Hopefully the drive then behaves fine and the light blinks continiously until the end of the burning.

The media is not written anything when the drive light goes green, and I was able to use it again fine in my next burn.

Anybody else experienced this? Is it a media related problem? I’m using some Philips +R and Fuji -Rs.

Every body have a happy holliday break!
