Well, I'm using firmware A07R and I'm not have any issues with it. Actually, I found that A07R burns CMC MAG.E01 better than A07M. At this point here is what I think you should do.
Update firmware to latest(A07R)
See if you get the power calibration errors anymore.
If not, great!
- If you still get power calibration errors then either
A. Keep the 1016IM, buy better media in future and burn the remaining LEADDATA01 disk in the 1008IM.
B. Return the 1016IM, get your money back and continue to use the 1008IM. IMHO, 16X disk and DL disk are too expensive right now anyway.
When I first started burning DVD's about 2 years ago, I bought some "cheap" media from and internet store (MID=AN31) and now the backups I made with the cheap disk skips in my new player. The 1016IM will still read the "cheap" disks, so I'm having to make new backups now. I'm not saying that you should exclusively buy TY media, but definately buy better quality. Once you find a combination of disk (MID code) and firmware that works for you, stick with it.
Also, in the future use DVDIdentifier to see who the MID is for the disk. This is what matters to the drive and how well it works with the disk. The name brand on the packaging isn't too important.
If the firmware update fixes the problem, please post the results so others might see the solution.
Remember, Garbage In(cheap disk), Garbage Out(bad burn)! Hope it all works out for ya!
