When burning DVD's (this does not happen when burning CD-R) my buffer (not device buffer) starts out at or near 100% but then gradually drops to around 1% or so (sometimes 0%). I thought it was my LG GH22NS30 so i bought a new ASUS DRW-24B1ST (with the new 1.04 firmware) and installed it today. but the same thing happens. The discs in use are Verbatim 16x (MCC 03RG20) and burn speed always set at 8x. Even though buffer drops like this I never get any Write Retries and the end result is always perfectly fine. I am just concerned and would like to know what the culprit may be.
My PC is fairly new too (just built it in September 2010 except for HardDrive(s)and Video Card (ATI 3870 Radeon HD). AMD 965BE 3.4ghz (stock), 4GB G. Skill Ripjaws 1600 DDR3 memory (2x2gb), ASRock 870 Extreme3 MOBO, 500GB 32mb cache Samsung ST3500320AS (OS Drive / Drive where all burning is done from) and 2TB 32mb cache Hitachi HDS722020ALA330. The only other devices plugged in is my keyboard and mouse (via 1 USB) and an XBOX360 controller. Typical programs running other than ImgBurn when i burn are Utorrent (I cap download at 300kb/s and upload is always at most 10kb/s), Trillian, Winamp, and 1 browser window. Having said all that i still have more than half of my memory free.
ImgBurn Log (see below) only shows 1 warning and it is the SPTD driver issue. Could the SPTD thing be the problem or what else could it be? Any help/info regarding my issue would be greatly appreciated. If any more info is needed i would be more than glad to get on top of it.
