Hey all.

I am having an issue where I am not always getting DVB-S signal. I have two Dual HVR 3000 tuners. If I force the other tuner to start up (by recording another channel) signal comes right.

I am running windows 7 23bit, with the latest drivers from Hauppauge.

Any ideas people?

Is the hvr 3000 the only sat receiver on the dish?

I used to have one and found that it wouldn't put out enough voltage to the LNB by itself, but we did have a couple of sat boxes, so I just made sure that 1 of them had the 12V LNB power turned on.

I'm thinking with 2 tuners pushing out 12v to the lnb, it is enough for it to kick in to life.

I have heard of a registry hack to increase the voltage out from the hvr3000, but there is the risk if it is set too high and a short developes in the wiring between the hvr3000 and the lnb it can cause an over current issue and damage the tuner or motherboard

It seems that at least one of the two has enough voltage as I can watch sometimes just one channel on that one.

For example tonight I was watching Channel A, and computer started recording channel b in the background.

When I tired of channel A, I tried flicking over to channel B but got a no signal screen. If I manually recorded another channel signal came back for channel B.

Does that make any sense?

if it shows A first ok then it won't be a power problem as obviously the lnb has powered up ok, I'm thinking a poor signal on the cable for b.

Are A and B fed from the same dish? If so are the fed from a dual LNB or fed thru a single LNB and a splitter?

Tried swapping the signal feeds, does the problem follow or stay with the same tuner?
