Can only burn on half the Speed. Y?

I'm currently using Pioneer 105's..Funny thing is ocurring..
Everytime I burn at 4x it only burns 2x etc..
Here's the specs:
Originally I had a Dual booth of Win98Se and Win2K..
I use Win2K mainly for DVD Burning..
Also The burners are Firewire External Cased..
I had update the ASPI Driver for Win2k..
I thought maybe Firewire enclosure was causing the half speed burn so I test it Internally but still same..
So Maybe it was softwares that was causing it but NOPE..
Then I removed the ASPI driver and let it burn then still nothing..
After that I'm thinking Maybe Win2K isn't too good with 105's burning so I updated to WinXp pro and yet still same..
What do you guys think? Suggestions?
I know it's not the Media or Burners b/c I tested them down someone's house and it does burn at 4x fine..
By the way I even changed the firmware thinking it would solve something..Not a damn thing!! I'm running Gradius's Hacked Firmware 1.33..Now b4 you're thinking that due to firmware I might be having the problems IT'S NOT!! Ask mentioned b4 It burns fine down someone's place..

hey there, I am currently using your same configuration. All execpt for the external enclosure. If the same media works on someone else's DVD burner, then you have to consider the differences,, Is theirs in an external enclosure?

Also, I just wanted to say that one time I bought some 4x media. And well, I was smoking a bit, and hit record on two dvds. It was set to MAx speed but it still wrote at 2x. When I noticed, I changed it to 4x manually and all was ok. But it hasnt happened again, maybe it was the media?

Thanks for the reply, but I mentioned that it wasn't the media or the Burner itself..I'm positive I could be wrong but it might ASPI layer that screwed up settings..Or something else..
I might have to format the PC.. :confused:

BTW, how do I adjusted manually? I always put the burn time on max..I think I tried it on 4x adjustment but nothing..
I don't know..I'm hoping Balto or someone could figure it out..

The 4X burners are real picky about maintaing the data rate. For instance, on an internal drive they often will not burn 4X unless DMA transfer is enabled.

I would start by diagnosing your connection issues. Maybe something is causing a slow down there, so your drive is not unlocking the 4X speed.

Scan your media with one of the tools listed above in the stickies. If your firmware updated properly, then your media should pass for 4X burning. If not, doublecheck your firmware update. There were some later revisions of the Pioneers that didn't want to work with some of the firmwares--you might need to investigate this further as well.

Keep us posted on what happens.

Good Luck!
