Problem burning xbox games on dvd+r

In the past I burned xbox games on dvd+r media and never had a problem playing them but now I burn them and evox doesn't recognize it only as unknown but I burn the same iso to a rw+ and it plays can someone please help me what has changed, getting upset I have lowered speed on burning and even changed burning programs no go PLEASE HELP?????

 

Have you changed the brand of the disk from the ones that used to work?

 

Ya but ya know what when I burn the iso to a dvdrw+ then copy it on my desktop it works so I uninstalled the burner drivers then restarted and it still won't play in it. The burners are the same kind, hp so I am really thrown for a loop here???????????

 

Some xbox drives dont like certain makes of dvd's

 

i was able to burn one using nero just click on copy an entire disc.
