Hi and welcome here at CDF,
you may find some answers to your questions in this thread.
You can make the +R and +R DL discs more compatible to older standalone DVD player by using the so called booktype or bitsetting. This means that you set the booktype of your +R or +R DL disk to DVD-ROM which makes your DVD player think that a pressed DVD is inserted but I've no Idea if your burner is able to do the bitsetting.
I hope this will answer some of your questions.
