no i havent s8-n , but do burners have heads (i make it sound like a tape deck) or something similar that might wear out , get dirty and need cleaning ??anything like that?? r u trying to go from one disk to the other? if so try going straight from the harddrive..? what sort of burner is it?
well hope u can sort this out soon cos i remeber having trouble with mine , made about 100 coasters... drives u nuts..
