Damaged streams when channels in same bouquet

[pp0815]

Hello! :-)

While playing or recording two channels from the same bouquet there are a lot artifacts.

Everything works very fine when the channels are in different bouquets, tested up to 6 HD streams. No problems at all.

Infos:

There is nothing in the logs which is relevant. What else can i do?

What do you think: problem exists in plugin or vdr?

Thanks a lot for your time and efforts.

I would rather bet on an issue with your SAT>IP Server. Receiving different channels from the same transponder is one functionality that has been tested and proofed in many setups with vdr & vdr-plugin-satip from the very beginning of the plugin. There's also a slight chance for a network issue, but since you say you can receive several channels in parallel from different transponders ...

Please, test with another program, whether you really can stream the whole mux without errors from your SAT>IP server. Using VLC with "pids=all" parameter should do the trick. The current channel URL is available via SVDRP command or setup menu and just replace possible "addpids/delpids" parameters with the mentioned "pids=all".

Thank for your very quick response, wow! :-)

Further tests shows, that the problem exists only for HD channels in one transponder in the vertical lowband. All other HD channels are horizontal and work without any problems, even all SD channels.

Sorry for that, - obviously the error is something completely different.

Thank you, have a nice day!
