Well after many years good service it looks like my SS1 has developed a fault

Heres the setup

3 seperate Dishes one on Astra 19e one on Hotbird 13E one on Thor 0.8w : 4 in 1 Diseqc switch.

The fault started when it wouldnt switch from one sat to another so i put it down to a faulty
Diseqc switch so i replaced it with a brahd new one but the fault was still there.
It just seems to lock onto i sat and refuses to switch to another.
Heres the funny thing if i connect each sat directly to the card each sat works ok.
Ive check all cables reinstalled drivers tried different versions of Prog but no luck
Unlees anyone knows any better.

Bison............

Would ProgDVB still do the band switching to HighBand, for example on Astra?
If so, the DiSEqC signal generator should be OK, too, as it uses the same HW stage.

Perhaps also compare with the original application from Technotrend.
