I've never had a single issue ripping or burning dvd's, but cd's are another story. I'd say about half of the attempts fail (makes great coasters). I using Nero (latest updates) and have tried TDK 48X and Memorex 52x blanks. Has anyone else experienced issues buring cd's? I also posted a few days ago, with no responses, about the Joint Ops expansion cd not being read. Well, magically today it is recognized.
On a side note to this, I seem to burn more coasters using Liggy's beta's, so I went back to the 2C8 (riplock removed) version. I stress, however, this is only with cd's. Dvd's work with no issues.
