[QUOTE=la1;2000514]I bought some ( windata:D) DVD DL RW media. I am having trouble burning the media. Seems they only work when burning if I make them multi session. If I burn another session or close the session the dvd will not be readable. I have an NEC , PIONEER and Umm Can not remeber the other make or model #s. I assure you they are popular model #s, DVD DL burners. I am using Nero 8 or 9 which ever is the newest, I even tried on ver 7. …Anyway I can not erase the media either.[/QUOTE]
I think you mean DVD+R DL media which always has the RW alliance logo on it.
Could you please use nero cd dvd speed and post the MID/mediacode from the disc info section?
