My 812@832S does not get a strategy for 16x Memorex CMC MAGM01 from firmware. Neither CG5J nor VSOM, the latest, have it. As a result, burns are rather bad/useless. However, I have a ton of these discs.
Meanwhile, I am running out of 16x Sony D21 discs which burn great at 4x and good at 8x (and have a strategy in firmware).
For lack of alternatives, I reassigned the Sony D21 strategy to a renamed (as CMC MAG M01 00) entry in a patched CG5J firmware set. Things look much better at 4x now. I’ll try 8x later but maybe some of you need this info sooner (the Memorex 100 pack was selling for about $30 at CompUSA recently.)
Here are are scans of the same material in Sony and Memorex discs - burned with Nero6. I hope it helps someone. If you know of other tweaks or strategies that may help more please let me know.
