I have 2 burners, A Pioneer 110d and a LiteOn 1693s and use to use Riteks in both. The Pioneer use to burn the g05s fine, But after I firmed up to the latest, They say incompat media installed, But work fine in the LiteOn. So I've changed over to TYs (Burned about 500 so far) and of those, Only maybe 2-3 have been bad and 1 time it was due to power failure. IMHO, TYs are the SHIT!!!!!!!!!
