In the past I have had problems reading 24x recorded disks on some readers. Try burning your ISO's at 8x (which is the only speed I will burn an ISO) and see how they fair with mediacheck. As a little check I just burned all 3 Rh 9 ISO's on the command line with RH 9 (note: magicdev was running) and mediachecked on 2 boxes and all passed. What follows is general stuff for people having problems with recording with RH 9. People are coming to the list telling of problems, but are offering up far too little information and hoping for a miracle fix. If folks could indicate the hardware they have i.e. recorders, readers, motherboard chipset etc. a common factor may appear with those having problems and help greatly. Just a thought! :) Regards Phil -- ICQ: 135463069 Email: philipwyett@xxxxxxxxxxxxx -- Public key: http://www.philipwyett.dsl.pipex.com/gpg/public_key.txt --
