DVD Automatically Ejecting Without Burning Completely

[army1506]

I am trying to burn a movie to a disc. I've done this so many times I've lost count. Always the same discs. Well now, the burning process gets to 99% and then the DVD ejects and then an error comes up saying there was an error while burning (Which is most likely from the disc not being in the dvd burner?). I have no clue what is going wrong, this has never happened before.
The movie is under a gig so its not a space problem. Any Ideas?

Notes:
-I am using Windows 7 Professional

-Burning with Windows DVD Maker

-Discs: Memorex DVD+Rdl 8x, 8.5gb, 240mins
(I've used these discs 25+ times for the same things and never had a problem, so i dont think its the discs, plus I've tried 3 other discs to see if it was a faulty one, but same thing happened)

1 possible reason is dust inside the player.
A solution is to remove the player, open the player and clean the lens.
You can find videos on YouTube on how to do this, it is actually a quick process.
