that is why everywhere i said "buffer underrun" with double-quotes!
Sorry if I overreacted, dodecahedron.
I didn't realize that you were using the quotation marks as a device to denote irony.
I was afraid that some dummy like me would read your comments and interpret them literally.

Thanks, QQ, I was hoping that someone with a system in your power range would respond with their high speed burning experience.
You have saved me the effort of cobbling together an old Gateway Pentium Pro 200 with a 140 watt power supply to run some tests. It's in pieces on the floor now, and I'll just put it away again.
In any event, it proves the point that burning is not particulary CPU intensive. DVD playback and MP3 encoding are more CPU intensive because of the respective decompression and compression involved. For instance burning a MP3 CD-R on the fly from WAV files on the hard drive is CPU intensive and could bog down an underpowered system, but this is because of the MP3 compression demands and not the burning requirements.
I'm sorry. I didn't mean to ruin your joke, Inertia.
Don't give it a thought, LiteOnGuy, it didn't make any difference.
I can't help wondering if your previous high speed burning difficulty with the Celeron 366 couldn't be DMA related. The symptoms seem that way. I know that you stated that DMA was enabled for all drives, but I have seen instances where the system shows that DMA is enabled but in fact it is not properly implemented. Frequently a change or update to the busmaster drivers or BIOS can fix this.
If you still have this system or have access to it, it would be interesting to run some transfer speed tests with CD Speed. Abnormally high CPU utilization is usually a giveaway that DMA is not working, whether or not the system says it is enabled.
