Burning ISO's directly to DVD's

Thanks
But I do not seem to get it. According to the post you are referring to, I should have a /dev/dvd-rw file (or something similar). I don't:

Am I missing something?

Maybe it might be because the Samsung USB drive actually is a BD drive as well? It DOES have the ability to write DVD's...
