I just upgraded from DVDfab 5.0.5 to 5.0.9. I have gsa-4163b RW and gdr-8162b ROM on one IDE channel, with no problems until now. Using SPTI.
Whenever the RW has a blank DVD in it, the DVD-ROM is not recognized by DVD fab until two minutes have passed. The drop-down box contains “please insert DVD disc …” during delay.
Ejecting the blank DVD before starting fab and the delay is gone.
