I'm having trouble with digital static-like artifacts on my HDTV recordings using the DVB drivers. This seems to be unrelated to signal strength, but noticeably impacted by system load. If I'm watching a recording or recording another channel on another tuner, the problem gets worse.
I know that my system has the throughput to handle the bandwidth, so it seems that there's some buffer that's too small, but I haven't been able to find it. This has been an issue with my HD-2000 card for several months, so it's not a recent driver change. My system: HD-2000 with rooftop antenna for ATSC (works fine with video4linux drivers) Air2PC HD-5000 with digital cable QAM (works perfectly with non-HD channels) Kernel: 2.6.14 with CVS DVB drivers (for HD-5000 support). All DVB drivers built into the kernel (not modules). Probably irrelevant: ivtv-0.4.0 for PVR-250 AMD 2500+ SATA drive nVidia FX5200 with xvmc
