Hiya Scammo,
The answer to your question is "it depends on your standalone". There is no "right" way to do this, because it is not a standard unto itself. But depending on the player, they may be a method that will work for you. My LITEON, for example, has no problems with just putting the files out there on an ISO DVD, but my Panasonic positively refuses to play those discs.
What model player do you have?
