|"when i put the disc in for nero after it formatted it first it said it was an incorrect disc for the project"|
You don't format the disc first, that would indicate you created a drag-to-disc (UDF format) type of format on the disc. That's probably why Nero said it was an incorrect disc for the project. All you should have had to do was fire up the video DVD creator part of Nero and use that to create the video DVD.
What was the exact message Nero gave you when it said you need to purchase additional things?
"I can burn it through wma"
Do you mean Windows Media Player? wma is an audio file format like mp3's, not a program.
