Here's what I have: S5 (6.0.1); Roxio Music Lab 10. I use mp3 320kps, and here lately SA no longer recognises the music files. At first the file plays well for a couple of seconds, and then it sounds like the speed takes off like a bat out of heck. In my terms a 45 rpm that moves to 78 rpm. The other 1400+ files that were on an S3 have no problems. Any ideas or thoughts? Is the Roxio software out of date? Thanks, Joe
