The pioneer hack is to do with firmware. This quite clearly isnt.
I've never had a problem with 3.1.6.0 and
DVD2One so im not in a position to say anything.
I dont and cant support 3.1.4.0 because it has other problems. You know how it is.... fix one thing, break another!
3.1.7.0 will be out soon and if that doesnt fix the d2O issues, nothing will!
