If you have a dual LNB on the dish you should have 10750 in all three.
If a single then 11300

No sorry. I've not used that program before, but did see that your settings were wrong for the ones I recognised.

The other options may be having an effect I don't know about.

If its a sky dish it wont be a universal LNB it will be standard 11300 or 10750 , check your transponder list and try searching from there

Most of the time it wouldn't matter too much, but if dvb1 has a dual headed Sky LNB then it is *not* advisable to use the same frequency in all 3 boxes. The decision logic is:

if (transponder frequency > switch) {
turn on 22k tone
use LOF 2
}
else {
turn off 22k tone
use LOF 1
}

The tone is important for the dual headed LNB. When it is off then the LNB is switched to Optus D1; when it is on then the LNB is switched to Optus D3. I'd advise either {11300, 12750, 11300} or {10750, 12750, 10750}.

@dvb1: check the transponder list in the software against the list -->here<--. It could be out of date. Also how have you connected the USB tuner? If to a loop out connection on the Sky box, remember that the Sky box must be on and you will only receive horizontal transponders. Similar considerations apply with a splitter arrangement.

It all depends on your LNB, but if you have the ex sky, Sharp, dual LNB the settings should be:

"Type" to KU circular
LOF1 10750
Switch 0
LOF2 10750.

Only have hte "Power" checked if you have no other decoders connected to the same dish/LNB and see if you can find Optus D1 in the satellite list. If none of that works I reccomend trying first NPVR and then MediaPortal. I have never used progDVB so can't comment on it but NPVR and MediaPortal are good.

Good luck, I know it can be frustrating.
