I thought that DVDs used a different filesystem format (UDF) than regular CDs (ISO9660). If this is true, then what you're probably seeing is "correct" behaviour - the ISO9660 code is reading stuff from the CD that is nonsensical (in an ISO9660 context) and it's crashing - hard. -- Matthew Emmerton || matt@gsicomp.on.ca GSI Computer Services || http://www.gsicomp.on.ca On Fri, 21 Dec 2001, Ross Lippert wrote: > > This is the first time I have used my DVD player on a DVD and not > a CD.
