Mahesh, welcome to Tom's Hardware Forum!
When you burn a DVD or a CD, you will be asked to pick one of two choices. It will ask you whether you want to use it as a 'flash drive' (not sure about the exact terminology, OR whether you want to play it on a DVD player.
Select the option for playing on the DVD player. Then proceed with instructions and burn. This DVD will only play on a DVD player, not on a computer.
Th 'flash drive' option will only work on a computer, and not on a DVD player.
The two are different.
I use Win 7 to burn DVDs and I burn both types.
