Hi,
i wonder, which of the following settings are optimal for the AVM 6490 (probably also 6590/6591).
RTP/AVP/TCP transport supported: ?
Full mux RX mode supported: ?
Maximum PIDs:32 ?
Maximum length of PIDs:127 ?
addpids/delpids supported: ?
Disable device/firmware-specific workarounds: ?

Thanks in advance
