Question about VDR

  • Hello all,

    i have installed VDR on my Media-PC for watching and recording dvb-s2
    (Satellite) channels.

    I have one question:

    I have a single sat-tuner (TechnoTrend S2-4600) with one sat cable directly

    connected with the sat-lnb. (It is a simple twin-lnb, one cable to the first floor

    and one cable to the second floor - no SCR (Unicable) config)

    It is possible to watch and record different channels at the same time?
    I tried this, but the channel i´m watching stops when the recording starts.
    Is this only possible when the two channels send their signals both horizontal
    or both vertical (I know the reseiver must provide different voltages for horizontal
    and vertical transmitted channels)

    I´m asking this question because it makes me wonder, why this works with my
    parents reseiver (they live on the first floor). It is a reseiver frome the
    "Deutsche Telekom" with a Magenta tv contract (I do not know the type / manufacturer).

    Thanks for your help in advance.

    Greeting

    Andy
