Remote Control stops working nzTivo 1.5

[Skolink]

For most programs try the following:

1. Make the TiVo Read/Write with rw
2. Then copy /etc/dflt_sysinit.conf to /etc/sysinit.conf
3. Now make your changes in /etc/sysinit.conf (never edit /etc/dflt_sysinit.conf)
4. When finished make the sytem read only again with ro
5. reboot

I have experienced the same things as sadrake.
I don't seem to have either of those files on my TiVo which is using the nzTiVo v1.5 image (August 2006).
Instead I edited /etc/rc.d/rc.sysinit.author
Is that correct?
