madoka Posted November 22, 2006 Share Posted November 22, 2006 (edited) During burning sessions, I expect the burner's LED to be on constantly, but sometimes it'll blink which suggests that it had to stop burning due to buffer underrun. I've increased the memory buffer to the maximum allowed, increased the device buffer refill threshold, and increased ImgBurn's thread priority, but to no avail. The ImgBurn log shows no anomaly, however, and disc verification always passes. After experimenting, it appears that moderate disk access (such as loading an application) will reliably trigger this. Moreover, the device buffer indicator do drop to dangerously low levels when it happens (which suggest that the buffer did empty momentarily). This doesn't make much sense: memory buffers should protected against this type of buffer underrun. Yet, it seems that ImgBurn couldn't fill the device buffer quickly enough. My computer is basically brand new, so I don't think CPU's the bottleneck. My burner's Pioneer DVR-111D. Am I just paranoid?

lfcrule1972 Posted November 22, 2006 Share Posted November 22, 2006 If BurnProof is still enabled in ImgBurn (it is by default) you shouldn't have any problems with your burnt disc. What drive are you using ? The reason I ask is that my BenQ DW1655 flashes whilst burning but the LED is solid in standby..... Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted November 22, 2006 Share Posted November 22, 2006 It could be something else on the bus that's stopping data from getting to the drive - especially if the pioneer is the slave device. Burn something and look at the write speed graph data via DVDInfoPro. Perhaps post up a screenshot or something so we can look too. Post the normal log too while you're at it please.

blutach Posted November 26, 2006 Share Posted November 26, 2006 Also check DMA Regards Link to comment Share on other sites More sharing options...
lfcrule1972 Posted November 27, 2006 Share Posted November 27, 2006 and maybe post back with an update ? Link to comment Share on other sites More sharing options...
karen cito Posted May 7, 2007 Share Posted May 7, 2007 Also check DMA Regards I had the same problem with a really slow DVD burn. The ImgBurn folks solved the problem for me. It turned out that Windows XP slows down the disks turning them from DMA to PIO without you knowing it. See the references at http://forum.imgburn.com/index.php?showtopic=4032 Good luck!
