I have ripped many cds with CDEX and have never had a problem till recently. There are about 2 cds in my collection that will not rip. I'm just making Mp3s for my local hard drive. The cd is Michael Sadler's Clear and the other was the last Stones cd. The songs look like they rip but skip all the way throgh. I have over 700 cds and these are the only two. Any recommendations?
