I have windows xp SP2, I have a LITE-ON DVDRW SOHW-1673S burner, I'm using nero CD/DVD recording software. I've got the WinXP IMAPI CD writing service disabled. I have TI 8 build 800. Have backed up 7 tib files, 6 635mb and 1 279mb tib file for a total of3.99GB onto my 2nd internal hard drive. I want to put the tib files on dvd+r's and dvd+rw's. When in nero burning rom do I choose dvd-rom(ISO)? or dvd-rom(udf)? or dvd-rom (udf/iso)? Do I choose start multisession disc? or no multisession disk? Under the ISO tab do I check the box saying "Do not add the '.1' ISO file version extension? Are the choices the same for dvd+r's and dvd-rw's? Thank you.
