Does anyone have ideas why I get corrupt video with TerraTec Cinergy 1200 DVB-C pci on Gigabyte P55M-UD2 motherboard and i5 750 cpu based system? Every few seconds the video gets messed up. If I decrease the number of cpu cores in use from the bios video artifacts become smaller or disappear (not entirely sure). Anysee E30 USB tuner works fine without problems with this setup. I've checked that the MB bios is newest available. Problem exist with both yavdr 0.5 and 0.6. The signal level that vdr reports is very good and does not seem to influence the problem, there are no jumps when video messes up.
The TerraTec card works fine with older setups, for example one based on Athlon X2 and Asus motherboard (AM2/3). But I would like to upgrade my setup to faster and wonder may I get similar problems with other newer hardware? On the other hand, should I consider giving up using old pci tuners?
