Bitsetting, booktype setting problem

I got a 812@832 and I’d like to be able to set the booktype on this burner sometimes.
I try using the booktype tool from Liteon, but it gives me an error saying no DVD writer detected.
I assume this is the usual method to do this.
I remember advice to use the instant bitsetting in KP2.
Should I forget ‘Booktype’ and just use KP2 instead?

The problem is probably an ASPI issue. If you have KP2 set to use SPTI, then that’s why KP2 works but booktype doesn’t.

But KP2 is better, because, at least w/ 2.2.3, it supports the instant bitsetting feature, which won’t be available for the booktype utility until a future version.
