[QUOTE=pinto2;2032513][I]Not all on topic.[/I] First of all, I’m not familiar with Buffalo firmwares but it should surprise me a lot if they use different write strategies to stock Pio firmware (this simply because write strategy change like Z-CAV to CAV is not that simple to alter, heh).
Anyway, my Pio 115D/115 use Z-CAV at 6x with DVD+R9 discs.
[And I like it this way because its faster then it would been with 6x CAV.]
As you’ve recognized in later posts, you meant Z-CLV, so you probably also realized that you should NOT like this, because what you are receiving is SLOWER than a true 6X CLV writing. Not only that, but check your written side - do you notice any “banding” or “ringing,” as others have called it? I could probably learn to live with simple banding, but I receive this strange zone with swirl marks. It’s hard for me to believe that the data is recorded as plainly in that area, or that it will allow it to be read as well when read back from the reflective layer.
It’s good to know that there are other Pioneer drives exhibiting the same behavior, but I have to wonder why Pioneer would remove the 6X CLV that worked very well with the DVR-111 series?! And in my case, the DVR-212 is definitely supposed to have true 6X CLV. See this link for verification:
where it clearly shows:
“10x Zone CLV (13.85 MB/sec)*2
8x Zone CLV (11.08 MB/sec)*2
6x CLV (8.31 MB/sec)
4x CLV (5.54 MB/sec)
2.4x CLV (3.32 MB/sec)”
So, why does Pioneer LIE about this? I purchased another Pioneer when I needed SATA specifically because it knew the the prior ones were able to burn DL media at 6X CLV, and the specs at this link verified that it still does! Pionner needs to learn something about truth in advertising…
Meanwhile your DVR-115D specs are detailed here:
where it says this for DVD+R DL media:
“10X Z-CLV (13.85 Mbytes/sec)*
Note: * This specification describes the maximum speed in one zone.”
So, that is consistent with what is written for 10X for the DVR-212, but they do not explicitly state that 6X CLV should be possible for your drive. I verified that this is the same for the DVR-215 series. Perhaps Pioneer decided to be ambiguous with this to provide wiggle room and the ability to deny 6X capability when disappointed customers call? I imagine they’ll remove the 6X CLV from the DVR-212 specs if they hear from enough people - I plan to call.
So, the question remains why these newer Pioneer drives, apparently both IDE and SATA are not capable of burning DVD+RL DL media at a true 6X CLV, when prior drives like the DVR-111L can? It is definitely possible because it burns single layer media at a true 6X CLV. Is it a different chipset perhaps, and they are trying to lower production costs? This is very disappointing! Unless this gets resolved, I’ll either have to live with 4X CLV writing (not acceptable) or move to another brand that offers true 6X CLV. I know my older NEC ND-4550A does this same 4X CLV to 6X CLV shifting when I choose 6X, so more research will be needed…
It also sounds like the shift points can not be modified or removed in the Pioneer firmware, so FIXING the DVR-212 firmware to do what it is supposed to appears to not be an option. :a
