Does the HN-10 support booktype to DVD-Rom

I was thinking of getting this to replace a Benq 1620 which from what I know has auto booktype, so I was wondering about the HN-10. Much appreciated. Thanks…

do you mean GSA-H10N?
it supports booktyping of DVD+R and DVD+R DL, not DVD+RW.
it does not do auto-bitsetting, but flashing with JJ11 firmware (hacked. thus will void your warranty) enables auto-bitsetting (among other things).
