Error writing ISO files to Ricoh DVD R

I am trying to write an ISO file that I built using the "build" mode in Imgburn. The ISO file is showing properly on the PC (a Dell E1405 Laptop with a Philips DVD+RW drive). When I start writing the same with Imgburn to a new blank DVD (Ricoh DVD sold by Office Depot under its brand) there are no errors in the writing phase - see image below.

Any help on what could be the problem and the solution is deeply appreciated. Thanks a lot.
