I just got an external LDW-851SX Liteon 8x Burner. It uses a USB 2.0 interface. My laptop is a compaq celeron 2 ghz with 256 MB ram. I learned that my laptop has the older USB 1.1, so when i tried burning a backup of my first dvd with DVD XCOPY XPRESS it took 2 hours to read the dvd and then it froze after 10 seconds of writing to the blank. I ordered a PCMCIA USB 2.0 adapter card that supposedly will give me USB 2.0 speeds to use the burner......my question is does anyone have a similar setup? will the usb 2.0 adapter work for me? and what media works well with the lite-on drive? i have a toshiba sd1200 dvd player that i believe only like DVD-R.....i bought a 50 pack of memorex i am going to try. any advice would be appreciated.
