Demo will not play songs

[herbyb]

i am using the plextor 740/a 1.02, latest firmware and drivers. i tried several cd's, some brand new. the demo recorded and burned everyhing i tried, the program hardly will get through any one track. the program reads and plays the discs without problem, it just can't seem to record properly. i think there is a 5 second pace between tracks, it records that nicely but then closes when it starts to record the track.
