In an earlier post I had stated some results about DL burning and even SL burning. I have since updated the firmware to A07M. This is the second firmware update since I bought the drive. Funny thing is there is no "change list" on the BTC site as to what is "new and improved". I did also state there is a new 1.08 bit set utiity out.
I had a DL Verbatim (MKM) disc left so I tried it. I used the 1.08 utility to set it to DVD-ROM and then used Nero 188.8.131.52 to burn Passion of the Christ. The A17J firmware already fixed the recognition issue with these MKM DL discs. Before they would only be seen at 2.4x even though the label said 4x compliant (in supported hardware). So the first firmware update made the 1016IM a "supported hardware"
It burned the DL disc in just under 26 minutes. It plays perfectly on my PC drives but still has issues with my Toshiba SD2300 and Sylvania DVD/VCR combo. This disc will also play fine in my Thompson drive based Xbox (which earlier burn tests would not). I have not tried my PS2 but I am sure it will have improved reliability as well. The nice thing is that in earlier tests with my Toshiba player, I couldn't even get to the main menu screen. It would freeze at the FBI warning. Now it will actually play to the main menu and let me select chapters before it freezes. So the new firmware has improved the burn reliability somewhat.
On 4x discs it has improved reliability greatly. I use Princo -R's and before this drive I was using the 1004IM and could burn and play in any of my systems. When I switched up to the 1016IM I could no longer play those Princo discs reliability in my Toshiba. The new firmware has fixed that. I have yet to try 8x +/- discs.
Nero now AUTOMATICALLY sets the booktype to DVD-ROM for -R but not for +R for some reason. I use DVD info pro and verify the book type has been changed after the disc is burned and every -R shows DVD-ROM (booktype) DVD-ROM (media type). +R does not change unless I use the 1.08 utility. Then only the booktype will change to DVD-ROM. Media type stays at DVD+R or DVD+R DL. Nero will say that it is setting the book type to DVD-ROM on both types of discs but only -R's are actually getting the treatment.
Once Dual layer -R discs become available, will BTC release a firmware update to allow DL burning on -R? Sorry for the long post but I like to be thorough with what I write.
