Just downloaded 4.2 md5sum checks out fine on all 4 disks. Burn iso's. Do media check and all 4 disks fail! Doubt if I have 4 bad disks in a row. CD reader loaded SuSE 9.2 perfectly on prior setup. CD reader begins to load K12ltsp 4.2 just fine until I abort the process. What am I missing here? Thanks Duane Wilson
