Hi all!

I just completed the installation of a 90cm offset dish pointing to IS5 @ 169 (BBC and Australia Network on C band) with another two offset LNBs pointing to Optus D1 @ 160 (Freeview) and Optus D2 @ 152;

When connected to the stand-alone STB, the signal strength is:
50% on IS5
98% on D1
80% on D2
All channels are tuning very well on the STB.

My problem is that I want to have them on my HTPC (see signature for configuration).
Until now I had only D1 and D2 and a tone switch worked perfectly with the HTPC for a couple of years. Now I have a 1x4 Diseqc switch and I could not find the correct way to set it up in Media Portal.

The STB has the possibility to set each of the satellites (under diseqc settings page) to "1 of 4", 2" of 4" and so on. This was very simple to set, as the diseqc switch has the connections labelled 1,2,3,4...so it was a no brainer... In just one minute all was completed...

But Media Portal has a different page when you set the diseqc, and I could not find a way to get it working.
If anyone succeded in doing this, any advice will be appreciated.

And one more thing: I tried everything I could think of, to get SBS, I played with the skew angle for hours and days with no luck. Any ideas about this one too?

Kind regards,
"aucklander"

Here comes the pain....Well it depends on the DVB-S card you're using. IIRC the BDA architecture doesn't implement diseqc so diseqc relies on manufacture specific methods in the driver to send diseqc commands which means that MediaPortal needs to support diseqc for that specific card. I had it working with a Technisat SkyStar2 but I had a huge amount of trouble with a technotrend card documented here:

Hi mcraenz,

I could not find the DVB-T Mapping tool for download anymore, do you have a valid link please? I have Avermedia Trinity card, hopefully it will work the same with this application.

One more issue: the diseqc switch has the connections labeled 1-2-3-4 and the options in MP and in this Mapper are AA-AB-BA-BB. What is the relationship between the two set of labels? 1=AA, 2=AB, 3=BA, 4=BB? I came across an article where people found out that it is not like that, it requires some trial-and-error work.

Yeah AA=1 Maybe! Yeah trial and error is in order. That tool is for the technotrend card only sorry. A few things to look in to:
1. What driver are you using? BDA? Is there a WDM driver? You could try that.
2.does the application that comes with the card work with diseqc?
3.what chipset does the card use maybe it's atually the same as some other more common card so you could use a better driver. E.g the Technotrend DVB-S budget is the same as the Hauppauge Nova S.
4.I think there is a table of supported cards and supported features on the MP site somewhere also worth searching/asking the forums. Again find out he chipset the brand may not be that important.

Aucklander: mcraenz is bang on the money. Trial and error! For what it is worth, I use DiSEqC with MediaPortal 1.0.2 and a 9x8 multi-switch. My settings require the use of the "SimpleA" and "SimpleB" options. The TV card has an NXP/Philips SAA7162 PCI-e bridge and TDA8263 (NXP/Philips)/MB86A16 (Fujitsu) satellite tuner/demodulator chips. Good luck!

Hi guys,

here is a picture of the DVB-S tuner: http://tinypic.com/r/2yjr7g5/3
If not working, you may try this: [IMG]http://i27.tinypic.com/2yjr7g5.jpg[/IMG]

I hope the numbers on the chips will help.
I did run the installation CD again (on a separate computer) and I believe the BDA drivers are installed (it was something on the screen about BDA).

Does this help in any way, please?
Should the application mapping the channels to DVB-T work?

Many thanks.

can I please have the DvbTMapper Tool? I could not find it anywhere, all links to Technotrend site are broken and there is nothing on their main site anyway.

You may email me to: dexter19702002@yahoo.com
Your help will be highly appreciated.

Many thanks.

As mentioned above that too is just for the technotrend cards. Also I don't thnk I have a copy anymore I don't have that card anymore. Did you get diseqc to work with the software which came with the card?

Hi!
Brief update: I managed to find the Technotrend DVB mapper tool, and as expected did not recognized the AverMedia card.

I had the "3-LNB + diseqc" setup hooked up to the STB for several days just to keep an eye on the signal levels, all good. Then I replaced the diseqc switch with the godd old ("MediaPortal compatible") 22kHz tone switch and I am using only two LNBs connected to the HTPC (Intelsat 5 for BBC and Optus @ 152 for other channels) - no Freeview and SBS.

I looked on eBay for a Technotrend card but they sell for around US$160 - 180 + postage. Quite pricey. I could add a second dvb-s card if I really want, but then I will have to run a second coax cable for the 3-rd LNB. This will also invole some PCI risers in the pc, which will only add to the cost.

I had a 2xLNB setup before, with both LNBs on Ku band with no issues. Now I have the tone switch with one C band and one Ku band LNB and it does not work as smooth as before. Quite often the PC freezes when changing to/from one of the dvb-s channels. Sometimes when it freezes the tone switch just makes a horible noise (buzzing continuously) until I have to press the restart button on the case! It never did that with 2xKu band LNbs.

I would gladly use the STB for the DVB-s channels I need (S-video to HTPC) but I understand the set-up of a IR repeater for the STB is another nightmare, not easy to set up at all...

Hi, I have a technotrend 3650-CI that I brought we us back from the UK - should I be able to get this to work with freeview satellite? no luck after a day of trying.

Thanks
