I used to have a LG 8x burner, but only for about 48 hours. The thing only made one good disc out of the first 12 I attempted to burn. Mine didn't like burning on any media with the green dye. It did one on a TDK, but I was so fed up with blanks that I returned it and got a Philips instead, which has been a joy ever since.
My burner did something similar. It would go through the process of burning, but either 1)hang after the first track or 2)go through the entire process of burning, but nothing would be on the CD. I used (and still use) Easy CD Creator 4, and after a few reinstalls of the program and borrowing Deluxe from someone, I couldn't get one CD to come out right until I used the blue dye media. I'm sure you've probably tried other media, but it might be the answer. All I know is I'm never getting another LG product.
