I purchased Xilisoft MP3 Burner 6 about a week ago. I bought it for burning files from my computer to making MP3 CD's for my car. What I got was a burner that produced the songs I wanted to MP3 CD but for what ever reason also produces a shortened version of each song. Example: I burn 75 files to a MP3 CD - I get 150 files. 75 good songs and 75 shortened versions. I sent 3 emails to the tech support and had no response yet. I don't know about the other functions of this program but if your buying this to burn MP3 CD's stay clear of this one.
