Just to add a bit to ripit’s suggestions.
I see you are also using DVD-RW media, many stand alone DVD palyers are unable to read this media, check your owners manual for your stand alone DVD player, it should list what media it plays.
I tried to do a search on your Sony DRX72OUL(Liteon Burner) but found nothing at all on that model #, are you sure that is the correct model # you posted?
This may be a bit overwhelming for you to understand but I’ll try to make it as simple as possible. Store bought DVD’s are not burned but pressed, the format used is DVD-Rom. Firmware is a set of instructions on how to burn a specific media, this firmware is software that is loaded into your DVD burners memory, it can be updated and is wise to do so because new media comes out frequently so the burner must be able to recognize it. Upgrading the firmware also fixes some bugs that may have been there on a previous version.
Some burners through their firmware have the ability to burn a disk to the DVD-Rom format, its called BITSETTING, thus fooling your DVD player into thinking it’s an original. This can only be done using DVD+ media, NOT DVD-.
The reason I say this because Liteon burners support bitsetting with the proper firmware.
I have burned over 400 dvd’s using the DVD-Rom format, they have been played in over a dozen players ranging from high quality to cheap crap, never did one of them fail to play in these players. Of course I only use quality media to avoid any media failures.
As ripit mentioned Maxell is good media but avoid Dynamax.
There is a CDfreaks Forum dedicated to the Liteon\Sony burners and have links for firmware as well as programs to install them such as the Omnipatcher.
It has comprehensive instructions on how to use it and install the firmware.

You’re probably thinking this guy is nuts, all I want to do is make a simple copy and he’s giving me rocket science. Welcome to the world of computers thinks aren’t as easy as we wish them to be.
Please advise if that is the proper Sony Burner model # and I’ll see what I can find out about it.
