Hi and welcome to the forum, trenton24!
If you are using the same brand of media as with your older burner and you now can't play them on the standard alone player, it sounds as either you applied book type setting on your previous burns or that the burns that the current burner produces are not good in quality.
You could post a log from one of your burns and/or do a scan of the burned disc with Nero DiscSpeed's scan disc function.
