I'm a complete Newby regarding burning DVDs and I didn't find any other users with this problem so far:
In My System there is a Plextor PX-W4824A CD-Writer and since today a Sony DW-U18A which I have crossflashed to 832 with the CG5G-Firmware.
Now, the LiteOn Tool Booktype V. 1.3.5 comes up with the error-message:
Unsupported Drive Detectet!
Drive Detectet but is not supported by this program!
And also the LiteOn Tool SmartBurn V. 3110 doesn't show any drives.
in Nero I can adjust the Booktype only if I use the CG5G-SonyID-Firmware!
BTW, ASPI-Layer 4.71.2 is Installed.
Just thought, some more information would be good
OS: Win XP Pro SP1
MoBo: Asus A7N8X-E Dlx
Just installed Kprobe.
It displays the drive-Names only with spi-driver.
With ASPI it says only 2-0-0-0, 2-0-1-0 and 5-0-0-0 (the bus-IDs I think)
