Why won't plextools do a q-check c1/c2 test on a dvd that was burned? plextools gives me an error "unable to read disc information. Please insert a cd." the only thing I can think off is I used bitsetting dvd+r to dvd-rom.
C1/C2 check is for CD's for DVD you need to do PI/PO tests Sum 8 and sum 1.
I fell for exactly the same thing when I first got my 716
