TBS 6909x Locking into multiple signals #163

Open JianSun1 opened 5 years ago

JianSun1 commented 5 years ago

I tried to lock multiple signals with different demodulators using TBS 6909x in Hotbird satellite. After locking into a few transponders, the transport stream output cuts itself and the demodulator never locks to another frequencies unless restarting the computer. I think the bandwith is high and the limit is exceeding. Could you fix this which auto distribute the maximum throughput or limit so i will not have to restart or reload the modules myself?

P.S. 6909x can receive up to 8 transponders DVB-S2 8PSK,30000 Ks. LDPC performace distributed btw all virtual demods (maximum performance 720 Mllr = 8 30Ms 3 bit per sym).

Confirmed an issue with this card on TVH. After locking to 1 clear UHD HEVC and 1 HD scrambled channels on 2 different transponders (it's just 2 not 8), TVH gets slower, and if tuned a few more - totally unresponsive until reboot. I can't believe I wasted so much money on this card. And no, driver isn't fixed. Older 6909 does NOT have this problem.

Floods with: mpegts: too much queued table input data (over 2MB) for TurboSight TBS 6909x (Octa DVB-S/S2/S2X) #11 : DVB-S #3, discarding new
