    Dual tuner streaming

    Multi LNB on a motor. One cable goes to TunerA, second to TunerB

    TunerA = positioner
    TunerB = second cable...

    Can stream any single channel with no issue.

    But if I watch a channel on TV, on few channels streaming a different channel (different transponder) is almost impossible (it breaks all the time). While the one on TV is fine or the other way round)

    But some combinations of 2 different channels is fine for simultaneous watching & streaming.

    So I do not think it is that H7 is not powerful enough to do that
    I think I have some settings incorrect.

    Is there a way for "force" channel to be received via specific Tuner?

    Thanks

    It should work fine as long as tuner A doesn't aim the dish away from what Tuner B is receiving.

    Should being the operative word. Some do, some do not. It is a single LNB with 2 cables out, so no way to aim it at something different!

    Excellent. 88-90. As I said, it only happens on some combinations of channels

    When the dish here was out of alignment and some signals were okay while others were weak or unusable I did find that when one tuner changing transponder could change the S/N ratio on the other enough to change it from weak but usable to not working at all.
    But if you have signals that bad something is wrong with the dish alignment, the LNB or the wiring.

    Can you tell us some of the combinations that work and don't work?

    Then what did you mean by positioner and motor here:

    That is not possible in the 'second cable from...' setup.

    @Sebus:
    1- Are all the channels involved FTA?
    2- What happens with the signal quality (SNR, not AGC) when you notice these issues?

    Have tested & redone both cables
    Each cable separate works fine

    But from quad LNB I can only stream a channel & watch another channel from the same TP (like describe here)

    It makes no difference if channels are enc or FTA

    Nobody? Is it supposed to work? Depends on the LNB? Used image?

    You need to be specific. Channel you are watching. Channel you are recording.

    It is all in first post

    There is no recording involved

    One channel on TV & another one streamed to PC

    Two DO work ONLY if both coming from same transponder

    Ok, so you don't want to provide the channel names. Also need settings file from /etc/enigma2.

    It does not matter what channels they are, it is the same for each & any pair (same transponder = both fine, different transponders = only first one "wins")
    Also it makes no difference in behaviour if they are FTA or encrypted channels
