I notice that whenever I burn a CD (I burn at 16x highest, 4x lowest), my buffer empties (and buffer underrun protection saves it) right after it fills up during the burn. What's happening is:
1. Buffer fills
2. Burn begins
3. During burning, new data isn't being read until buffer comes close to emptying (burn pauses to refill buffer)
4. After burn is complete, I notice the buffer underrun protection was used up to 20 times in some cases.
This happens no matter what software I use, no matter what blanks, what speed, and no matter what kind of disc I'm burning. I'm running Windows XP Professional SP1, and have DMA enabled.
If anyone can answer my question or solve my problem, let me know.
