i dont have a liteon writer but i do have the 165h dvdrom and it lets me test c1:). this is good but the problem is that when i read at max speed there are heaps of c1 errors. we are talking about 600-1000. no c2 of course but why is this happenening? i know my burns are better than that especailly with TY media. is it just a problem with the program or the dvdrom or both?
