Not really. DViCo Fusion dual digital tv card. One side of the card would yield "black video screen" when starting a digital capture sometime after (?) the VDR ATSC EPG plugin tried to suck off data. I'm not sure there was a causal relationship. I hypothesized that one side of the dual-tuner was going stupid or one of the two channels used in the cx23885 was getting confused. I was looking at how to narrow the problem down to cx23885 chip or xc5000 tuner, or s5h14xx demod when I noted the power managment module option for the xc5000. I suggested Tim try it. It was dumb luck that my guess actually made his symptoms go away. That's all I know.
