I have a SonyDVDrw DRU-510A and it seems to burn fast just half-way, then slows to a crawl, even when recording a standard music CDr.
The CD drive is all alone on the secondary IDE channel motherboard connection.
The DMA is set "if available" (Windows XP) in transfer mode (ultra DMA mode 2).
CPU is an AMD 3000+.
Why does this do this slow-down trick half-way? Has anyone heard of this before. Any suggestions to tweak a setting somewhere?
