Hi,

I have two hauppauge nova splus cards running with mediaportal.
I tuned in all the freeview channels and sbs channels.

I notice that sometimes when I try and view sbs channels they work others they don't..
Today I seem unable to view sbs at all..

I have read that while viewing freeview you cant view sbs but I have made sure that nothing is viewing freeview at the same time...  Anyone have any ideas on this? could mediaportal be holding the lnb the wrong way?
Is there anyway I can specify for mediaportal to make sure it changes the lnb orientation when it moves to sbs and back to freeview etc?

I assume that is the issue anyway...

Any help/advise would be much appreciated.

also... the freeview channels are crystal clear but when i can view sbs it breaks up quite a bit...
is that strange considering its coming from the same dish?

I think the SBS channels have a weaker signal then the Freeview ones here, Sometimes when the weathers bad I loose them. An AMP or a bigger dish might help but theres a cost of course.

You can watch Freeview and SBS at the same time ( or at least you can on my cheap Zinwell Freeview box) , perhaps it depends on the box/card selecting to view Horizontal or Vertical polarization.
The SBS signal is weaker than the freeview one and seems to vary during the course of the day, this morning 6am  only had a signal strength of 67% (not watchable) this evening  8pm 80% (crystal clear). Not a cloud/rain in the sky at either time.
Does anyone else notice this daily variation?

You are exactly right, you can watch Freeview and SBS at the same time but need an LNB capable of running horizontal/vertical polarities at the same time (which will almost always run 2 cables) where sky dishes LNB's only run vertical or horizontal at any one time.
In essence, all you need to do is replace the LNB and run an extra cable and you can watch SBS/freeview at the same time without issues.

I too have noticed varying strength on SBS. Usually it is associated with bad weather but there has been a couple of times where I have had bad signal on reasonably nice days.

Seems I`ve struck lucky then I only have one cable/LNB  (Dick Smith/Sharp) and can get both polarizations.
Upgraded my dish yesterday from 65cm > 90cm, no more problems watching ALL the live world cup games :-)

Not lucky, a standard LNB can do both polarisations just not simultaneously, eg you cant watch a channel on freeview and a channel on sbs at the same time, its not possible unless you have a dual output LNB.
