It seems you can use Diseqc on the HDR 1000S.
Getting to the hidden menu is documented elsewhere.
You pick your satellite - mine was Hotbird.
You pick the Switch Type as Diseqc B
LNB Frequency Normal
For 22kh switch you choose On rather than Auto - I think that was where I was going wrong last time. I had left it on Auto.
Oddlly when you pick the frequency you want to scan you often get zero Strength and Quality. On the old Humax HDR you saw when you were accessing a live frequency. However, if you then choose to Scan you should find some stations.
Not a great aide memoir or guide I am afraid. But the good news is that this particular machine will pick up non FreeSat satellites if you have access to the appropriate dish(es).
