The used read buffer (top one) doesn't decrease and is always full, but the bottom buffer fluctuates between 100% and (presumably) 0-20% like a schizo winamp visualization.

I've searched through the forums and I couldn't come up with anything to help me. I've tried setting 1' and 2' controllers to DMA and uninstalling them...also, I've updated my firmware and all the drivers I can think of.

This is my setup:

Windows XP sp1
Nero burning rom 6.6.0.16
NEC ND-3520AW DVD+/-R Drive w/ updated firmware
USB 2.0 enclosure w/ Cypress chipset (CY7C68300A?)
Viatech Via 6202 USB 2.0 PC card

and I know this is powerful enough to burn at at least 4x:
1.7ghz Pentium4m (inspiron 2650)
256 ram

*sigh* Hope someone can help. I'm tearing out my hair here...a simple 4 gb burn takes 40 minutes! That's slower than 1x.

You have pretty low computer specs. A RAM upgrade would definitly help. Are you multitasking? That will throw the burner off, esspecially with low ram.

Thanks for the fast reply. I'm not sure computer power is a problem for this setup. I had the same card/enclosure/drive setup on a 900mhz laptop running Windows 98 and that worked fine (9 - 22 min for 4gb).

Not only that, but I've tuned this XP computer to use zero graphics features, and went through Black Viper's XP guide. (Hmm...Can it be a service I turned off?) I assure you I don't multitask w/ CD burning, I know where that road leads and it's not a good place.

EDIT: I've checked out this setup on a 400mhz Win98 computer w/ 64mb RAM, and this is what happend: the (bottom) buffer level completely depletes itself, then the (top) used read buffer also depletes, then the drive writes a few meg's worth of data, then pauses while the buffers replenish. The burns are fine.
...Unfortunately even that is faster than the XP setup with just the bottom buffer fluctuating and the drive constantly writing and stopping (drive light green->orange->green).

- nice analogy!

let's have LAST section of your Nero log which lives in c:\program files\ahead\nero\nerohistory.log but DO NOT post your serial number which usually begins with '1A21' or similar.

You can differentiate sections via this section divider "====== *** Nero-Burning Rom, History File *** ======"



Main PC ~ Intel C2Q Q6600 (G0 Stepping)/Gigabyte GA-EP45-DS3/2GB Crucial Ballistix PC2-8500/Zalman CNPS9700/Antec 900/Corsair HX 620W
Network ~ DD-WRT ~ 2node WDS-WPA2/AES ~ Buffalo WHR-G54S. 3node WPA2/AES ~ WRT54GS v6 (inc. WEP BSSID), WRT54G v2, WRT54G2 v1. *** Forum Rules ***
