Tvheadend

I'm using a Sundtek MediaTV Pro III ([[http://sundtek.com/shop/Digital-TV-Sticks-oxid/Sundtek-MediaTV-Pro-DVB-C/T/T2-FM-Radio-AnalogTV.html]]) with TVheadend (master) on a Raspberry Pi 3. The device has 15 HW PID filters in total but, it seems that TVheadend uses all of them, when I tune to one channel. When all 15 HW PID filters are used and still another one is requested the Sundtek driver disables hardware PID filtering. With HW PID filtering I experience way better streaming quality without stuttering and stalls. Is it somehow possible to limit the amount of usable PID filters in TVheadend? If not, could that be implemented? VDR ([[http://www.tvdr.de/]]) for example allocates fewer PIDs and HW PID filtering is not disabled. Following [[http://forum.dvblogic.com/viewtopic.php?f=97&t=26731&p=85878&sid=7dac5783dfba92c0ab7703062d15c7b2]] DVBServer seems to act the same as TVheadend as opposed to VDR.

If you need further information, please ask.
