Synopsis:

Hello,
I am testing MP since 3 weeks and I have many troubles with autotune.
My 2 nova-s plus works fine with mce 2005 and the original-hauppauge-SW. That means too, that diseqc works very good. I have a multiswitch for astra and hotbird.
Now I have find out, after several tests, that:
1. MP (Level A/A, B/A) sends no diseqc-Info to the multiswitch (msw) to switch in highband. But here comes a 22-kHz-signal and the msw switch to hotbird.
2. autotune is scanning only the lowband. At the mark 11700 autotune scan with the astra-channel-infos the hotbird-transponder. Because the frequencies here are not correct, the AFC of the nova will catch only some channels from hotbird.
3. really example:
at the skip to 11.895 autotune goes to hotbird to the channel CCTV instaed to astra-highband. But this channel has the correct F=11.034.
You can browse the TV-tables with sql-lite-browser (find in the mp-docs-directory). Here can you see the frequencies of tvdatabase.
The different between the real value and the wrong value is
850 MHz. This is too the different between LNB0 and LNB1 and shows, that there is no switching to the highband. You can see this also, when autotuning find "updated" programs in the first seek-running.
P.S. Astra 19,2 and hotbird 13 have more than 2000 !!! channels !
autotune find max 600 channels.

I think, this problem is very important to clear, because many users have problems with autotuning in diseqc. I cannot change from mce to MP till this problem is away. And I cannot buy every week another dvb-s-card for new tests.

To the developers: This is really important for the acceptance of MP
look also here:

https://forum.team-mediaportal.com/viewtopic.php?t=8927

The core-problem seems to be this:
The BDA specifications are very weak about LNB
There is no clear specifications on how to select a specific LNB
This has resulted that today there are 2 different ways of doing this

1. General BDA LNB selection
2. Vendor BDA LNB selection

Mediaportal,My Theathre and TVCentral use option 2
some other apps use option 1

However whether it works or not greatly depends on your DVB card
if you card only supports option 1 and MP is using option 2
then it wont work:-(

NEW INFOS !!!!
At the beginning of my tests with mp, I have noticed, that when I changed to mce, I have troubles in mce with my channels. After reboot mce was good again. When I have looked a channel in highband on ASTRA, I can make a scan in mp in highband, too.

This effect is equal to the posting https://forum.team-mediaportal.com/viewtopic.php?t=8927

Now I have tested with the hauppauge WINTV2000. I have installed it from the win32-drivers, but using the bda-drivers.

Now you make a complete scan and you will find all ASTRA and HOTBIRD-CHANNELS !!!!!

Now you select e.g. PRO7,12.480 V, and watch this program onetimes in WINTV2000. Then you close this programm and go to MP and make a scan. You will find all highband-channels, but only Vertical !!
You can try this with all 4 possibilities for ASTRA.
With hotbird you have 8 possibilities.

This means, WINTV2000 replaced the missing or wrong diseqc-function in MP and can operate as a diseqc-selector.

If you have 2x NOVA-S PLUS, you must select card2 in MP, because WINTV2000 select card2 as first card. If you select card1, you dont have any effects by diseqc-selecting by WINTV2000 !!!!!!


Here you can download my astra-diseqc-test.tpl
http://www.joerg-sunkel.de/Astra-diseqc-test.tpl
The tpl contains for each band and polarisation one channel.
10.832 H x Bibel TV
10.979 V x European Home Shopping
11.739 V x MTV Central (Germany)
11.798 H x Premiere Start

So you don´t need a full scan to test diseqc.

Good tests !!!!! :)

The developers must now fixed this bug. They are not far away from a good result for MP. :)


I have found in the sourcecode of DVBGraphBDA.cs two
Ways of writing of DISEQC
1. diseqc
2. disecq

Is this the bug ???????????????????????????????????????


Many thanks for any reply :)




Excuse my bad english and many greetings from germany :wink:
