Will not finalize on toshiba laptop

Strange things going on here. I’ve had DVDfab gold on this pc for almost a year now but for the last 4 or 5 updates it says that it is finalizing but when I go to play it , Nothing. The funny part of it is that if I burn it to a DVD/RW it will work fine, but if I burn to a DVD/r it won’t work. I can finalize using the procedure outlined in another thread. It only does it on this laptop Satellite L35 S2161. I have done a clean uninstall as outlined on this forum twice now but still the same thing. Wonder if anyone has a suggestion. Thanks
