The problem lies with the modules Being exactly the same. Both 0500 as CAID. The hardware/software simply can't differentiate. Only the Duo4K and DM9*0 can.

Hello mimisiku,

Sorry to revive this 9 month old discussion, but I wanted to know more about this reply from you.

My cable provider encrypts all channels (except 1), and the use of a CI+ module is mandatory.

I had a VU+ Duo2 (not 4K), and I tried to use it with 2 identical CI+ modules, but I had a black screen instead of the picture after inserting the second CI+ module. I saw the information that the Duo 4K (not SE) was able to do manage it, so I bought a used one. I was hoping to make the Picture-in-picture work with 2 encrypted channels.

The farthest I went, I managed to have 2 channels displayed together in PIP, but only when they are on the same transponder, which is too restrictive for me.

I tried with every advice found in this thread/forum and others as well (CI assignement plugin or not, multiple services, ...).  I even tried duplicating the list of channels into 2 ranges : 1-100 and 101-200 (by editing the file userbouquet.favourites.tv), and assigning all 0xx channels to card 1, and assigning all 1xx channels to card 2, but that did not solve the problem.  Note that I have only 1 DVB-C tuner with 8 channels (FBC).

It is disappointing, because on my "big brand" recorder (Panasonic DMR-BCT76), the dual CI+ module works in a very stable way, just Plug and Play, similar to my Duo with 1 CI+ (although it implements very strictly all the DRM restrictions).

I forgot to say that I use VTi 15.  I considered switching to OpenPLI 8.1, which also provides CI+ decryption, I found the 3 required .PEM files, but not the "param" file, so I gave up this possibility. I will probably be able to use it when this functionality will be more broadly used.

I have a question for you : what specifically is different between the Duo 4K and the Duo 4K SE (except the CPU) ? is it the card reader hardware ? or the kernel drivers ?

Thanks in advance,

Best regards,
