I believe poor quality media is your whole problem. The companies you mentioned just farm out their manufacturing to the lowest-bidder factories and re-bag the media with their brand names. They have taken our over-lobbied Washington DC's policies of allowing big business to "outsource" to it's highest, nightmare level. Memorex, in particular (but the others mentioned too), should be prosecuted via class action for taking people's money and providing worthless product all these years. They change manufacuring specs often even though the retail packaging looks the same. And disk quality often varies within the same damn spindle of disks!
So, would you recommend I read up on "strategy switches" or, first, try it at 8X instead of 16X?
I don't understand why people fool around with procedures like this ... just buy good media and booktype to ROM. And, with your 1693 burner in particular, burn at half the rated speed of the media as posted above. BenQ burners are a bit more reliable at faster speeds (and booktype flawlessly) but I still recommend that you never set CloneDVD to burn at "MAX" (set it at least one or two notches below the media rated speed) even with the BenQ burners.
Get rid of ALL the media you currently possess. Return them if possible or just throw them out and consider it a lesson learned.Stop using cost per disk as your criteria for purchase. Stop buying in your local stores if these are the only selections offered. Shop online to get what you need. Good media is just about the same price as the store-shelf junk you are now buying when bought in bulk spindles of 50-100.
Buy Taiyo Yuden, Verbatim, or Sony (if the label says Made in Japan). Some cdf members like Fuji (if mij) and may also post that on this thread. Again, poorly rated media is your whole problem. Even if you can get your burn to work in your player today, your backups will stop working in six to twelve months and you will get the famous "No Disk" or "Dirty Disk" error message from you player.
Also check monthly (at least) for firmware updates for your LiteOn burner. The whole purpose of firmware updates is to include new media recognition information for your burner (but don't count on the poor media companies to even report new specs to the burner manufacturers for inclusion in firmware updates).
