Description

I'm struggling to find out why low bitrate (1-3 mbit/s) h264 SD channels via my HW CAM are totally crap. Higher bitrate channels (HD), > 3-15 mbit/s are always fine.I'm using the TBs5881 DVB-T/T2 with HW CAM. With dvblast it's normally ok but with tvh I have this issue 9 times of 10 when selecting an SD channel. HD channels uses DVB-T2 and SD channels uses DVB-T but not relevant I guess. I have tried to play with the buffers etc without any luck. I attach one file from one single channel and one file for the whole one mux.
