[chudm]

What's up guys how are u doing, i own a Lg gsa-4160b dvd writer, since... 5 months , the dvd writer was working perfect, but at one disc while was burning it, gives me an error something like : failed to focus or something like that, so i try to burn again the disc and then burn it ok, but when i saw the back part of the dvd i saw a ring almost at the end of the border of the dvd, when i tried to make an iso file of the disc worked perfect until 98% then cant be read it, that happens several times until i restarted the pc, then worked ok, i will try to burn other disc soon, btw i used RITEK G05 disc, that always worked perfect for me, any comment about that really weird problem?thx in advance, i hope that my dvd writer inst dying so soon

What software do you use to burn the DVD?
The ring at the outer edge is where no data has been written,its normal to see that.

I use nero, but no, isnt the normal ring, its a ring in the writed area
