    Is there any benefit to trying this out on a system thats currently working without problem? LiveTV will get used extensively for a few days from now if more guinea pigs are needed.

    Can you disable your DVB-T card and test with just the DVB-S card as your signal is really weak on the DVB-T card. Try both clients with just the DVB-S and let me know how you get on.

    Thanks.

    So, I switched dvb-t off. But I got problems, too.
    Here are the results:
    1. switch Client 1 on --> no problem
    2. switch Client 2 on, same channel --> no problem
    3. change Client 2 to other channel, same transponder -> first client stops working (standing picture), client 2 works well
    4. stop client 2
    5. client 1 works with some esc and mouse clicks...

    Thats a new behavior...

    It's configuert as usal, which means there is a 0 as limit. I changed back to the normal tswriter.ax which comes with 1.3 beta. There I can watch two dvb-s channels without problems?? Only issue is watching dvb-s and dvb-t together causes some problems thats was no topic in former versions???

    So perhaps there are more than one issue in 1.3 beta? Give me a hint how to seperate this errors? First it's important to fix the tswriter issue!?

    Update:

    I chnage backt to version 4; its the best of all test versions. dvb-s AND dvb-t are running for hours without problmes. Started yesterday evening, it's still working. Version 5 crashes after several minutes each time I tried...

    Hi DJBlu,

    just took a look at the last state of your git branch and recognized that you didn't remove the autolock in tswriter.cpp at function

    "STDMETHODIMP CMpTs::NonDelegatingQueryInterface(REFIID riid, void ** ppv)"

    It's important to remove this autolock as this may lead to dead locks as threads may take possession of the critical section multiple times within the interface calls.
