i used to be able to booktype dvd's when i had the exact same optical drives but w/ a different motherboard and processor. before, i had an AthlonXP 1700+ Tbred A mildly overclocked to 2100+ speed and a Gigabyte AMD 761 chipset board, w/ 768mb of Crucial pc2100 ram. now i have a mobile barton 2600+ overclocked to 2400mhz, and an Abit NF7-S. i've switched to using a 80gb Western Digital w/ the abit ata to sata convertor that came w/ the mobo. well now i can't booktype w/ my 451S@851s. i used to be able too, but Kprobe 1.1.29 says it's still DVD+R, although the BookType utilitly v1.0 says it did change. how can i fix this? is it my set up, or is it my dvd-rw or what?
