Not sure what time it is where you are but here in the UK you posted your message at 4:02 am and then the chaser at 6:17am, most forum members are not around in the wee small hours
I would guess that your problem might be your media, in other words the blank discs you are using. Have you had any problems with these before ? From the log it looks like the drive is having problems writing to them. I just tried to find firmware for your drive at
http://forum.rpc1.org/dl_search.php
but couldn't find anything, the drive ID of "DVDRW IDE" seems very generic - what make is it ? ImgBurn might be able to check the firmware for you, with the program open right click on the GUI where you see the drive details and from the list select "Check for firmware Updates". See what that finds.....
Did you see any error messages during the burn ?
If you have any other discs I would try that as well, we recommend Verbatim (MCC dye) or Taiyo Yuden (TYG02 or TYG03) on the forum as being far more reliable.
