I have been trying to burn at 8X using Nero 18.104.22.168 but have had no luck. I have an LG GSA-4160B in an external USB 2.0 enclosure connected to my laptop with a USB2.0/Firewire PCMCIA card. I have tried both CMC and TDX 8X discs with the same results I don't get any coasters but I just can't seem to burn at the speed it is supposed to be able to do. I have trawled through the forums with no success (check DMA, defrag the disk etc). I am confident it is not the transfer speed. A speed check on Nero indicates I should be able to transfer at 13X. Transferring files to an external USB HDD easiy out performs the 11,000kBps required for an 8X burn. Although I don't have the SCSI error described in this thread http://forums.afterdawn.com/thread_view.cfm/102002 I have tried all the suggestions with no luck. Whenever I attempt an 8X burn, the buffer fluctuates between 99% and 30% for about 10mins and then stablises at 99%. The burn completes in about 30min, equivalent to 2X. When burning at 4X, this buffer is stable at 99% orvery close to it. I'm not sure what else to try. I've noticed that nero 22.214.171.124 is out but the release notes do not indicate anything that will help me. Does anybody have any ideas? Thanks in advance.
