Let's see. What have you told about the physical connections of your receiver so far? Nothing really. Obviously you have something hooked into tuner A or you would not be using Tuner A. It might help to describe in detail the cabling, switches, or anything else that is connected to tuner A.

Then there is tuner C. How is the usb ATSC tuner connected to the receiver? Is it plugged directly into the receiver? Are you using a short extension cable or usb hub?  How is tuner C connected to the terrestrial antenna? Preamps, Splitters, Amplifiers, Ground blocks...etc.

Tuner A: 4 lnbs connected to a 8 x1 diseqc switch (Capable of 8 LNBs). Each LNB (satellite) is configured as Universal, Voltage mode: Polarization, Tone mode: Band, Diseqc mode: 1.0, Diseqc q.0 command: A, B, C, D (each letter assigned to each lnb.

Tuner C: Antenna, 4 way splitter (4 TVs), cable connected directly from the splitter to the Hauppauge 950Q , and this last one connected directly to the USB port of the receiver (back usb port).

Note: The same configuration is working perfectly on TNAP 4.1. 

Hi
 What is "OpenPli last image" supposed to be?
 Images have numbers. It helps to know what Image is actually loaded in the receiver (Menu--->Information--->About).

 In general, the problem you describe could probably be traced to bad cabling or improper receiver settings.

What are the receiver setting that I have to check?

Hi

The OpenPli version is the 8.3. Bad cabling? I think if it were bad cabling the problem will continue after rebooting. When I mean rebooting is the complete receiver, not the rebooting of the image. Doing this last one, the problem is not solved at all.

Try changing a setting. 
Go to the Customize menu (Menu--->Setup--->System--->Customize). Scroll down and change Ignore DVB-S namespace sub network to "No" as shown in the attachment.  Make this change, delete the problem channels and re-scan before doing anything else.

It might be possible to edit directly the lamedb file located in /etc/enigma2 of the receiver files, but at best doing that will be messy.
 

It would help if you showed us exactly what the problem is.  A blindscan log of found transponders is made every time a blindscan completes. This log is located in the /tmp folder of your receiver. It might help to post that log. OR give at least the correct frequency, symbol rate and polarization of the two transponders you are having problems with along with their channels. But try changing the setting first and see if that fixes it.

 

I went with a shortcut. Restart with TNAP image, did a blidscan on problematic satellite, saved channels of interest in favorites, flashed OpenPli and when asked "Restore setting". I selected Yes, and Eureka. it got all favorites from TNAP image. Finito!!

You can delete the channels for a satellite that you have made a bouquet for, and none of the bouquet channels will work. You can re-scan the satellite and the bouquets will usually work again, provided the transponder information does not change in the re-scan.
 

Probably the best thing to do with problem or non-working channels in a bouquet is to delete them. Bouquet channels depend on the channels in the lamedb file. If the information in the lamedb file changes then the bouquet channels will not work.

 

I've tested different options and images. I've forgotten about bouquets. I just did a blindscan on the satellite selecting only two transponders. With TNAP there is no problem, it seem that this image is capable of differentiate both transponders easily, but with OpenTV and OpenPli, once the transponders are scanned they save the info of both transponders as if they were the same transponder, assigning the same SR to all the channels, then it is no possible to lock the channels with different SR as the one assigned by the image. I think, that what is left is to edit the lamedb file to add the missing transponder info and assign this info to the channels with the modified SR and transponder. Would you have any info about how to edit this file?
