Hey guys! First off I've been running the search engine in this site trying to avoid to start a new topic regarding BUFFER LEVEL UNDERRUN. I have burned over 150 dvd's with no problem before. As you know, when we burn with DVD-Video, normally it says 14-15 minutes countdown how long the DVD will take to burn where it did before. The buffer level use to be 95% and higher consistently and burn at the given time. Now it takes about 20 minutes minimum to 25 minutes burning. The disc are 4X. I have tried Verbatim, TDK, and Maxell. They were working fine but now underrun. The buffer level jumps from 93%, 16%, 45%, 98% and so forth rapidly. I have tried the Device Manager and all are set at DMA not PIO. I have reinstalled Nero. I have defragmented also. If you want some specs on my computer which I find elite is: P4 2.8ghz 800 FSB, 80gb, 1.25 gb of DDR RAM. Yes it is 1.25gb of RAM, I'm a advance gamer. So please don't tell me that my CPU is not equipped to burn. So please any suggestions will be great.
