I own a Sony VAIO VPCEA35FL Laptop, and I'm having problems burning CDs/DVDs. It seems that the burn process itself works, but once the disc is done, it can't be played. I tried Brasero and k3b, both without success. Sometimes the TOC can be read without a problem, but the data never is readable. Also, when I try to play video DVDs, the dvd drive becomes noisier and usually the video stops for a few seconds. This is a weird behavior, since a couple days ago I was using another O.S. and it worked just fine.
I think that this wasn't a problem using Natty.
What can I do?
