I use popcorn to burn dvd's on my g4 power book w/ superdrive I use dvd-r and until last week have had no problems. Now when I insert a blank dvd-r the drive will not recognize it. It makes a few not-so-funny little sounds like it's trying to recognize the disc then it ejects it. I have no problem burning cd's or playing dvd's. So do ya think my dvd writer is trashed or is it a software issue ? thanks geotech
