I have a Toshiba Satellite A75-S209 in which I had a Toshiba CD/DVDW SD-R6472 professionally installed. I am using Nero 18.104.22.168. My problem is that 'somtimes' while usung Nero Recode I get an "illegal disc" message at the end of the burn stage, it seems that my burner will not finalize the DVD for some reason. With the same DVD's I can however opt to first recode the files to the hard drive and then burn them no problem. Any help or insight would be gratly appreciated.
