I don't think so. It's likely that no one has a good answer/solution. I don't use the same usb device you're using so I can't be of much help, unfortunately. However, with my own usb device (OnAir Creator) I also encounter the black screen when trying to display from the composite input. I have been in contact with one of the developers but I now need to test under Windows and I don't have access to windows machines, so that's the holdup until I manage to find one where I could install the manufacturer's driver and software. You might try your setup under windows, if you have access to such a machine. When I asked about my black screen issue here, I was pointed to http://www.isely.net/pvrusb2/usage.html#V4L I have tried mplayer in pvr mode $ mplayer -tv input=1:normid=16 pvr:// For my device, input=1 is the composite input, 2 is the S-video, but the camera I'm connecting has only composite, no S-video, so I can't test the S-video input. Normid=16 is the first NTSC video standard, NTSC-M if I remember correctly, but I tried all of them: no difference. You might want to test with mplayer, it gives pretty verbose output and it describes all the video standards supported and inputs of the device. I see that you use PAL-DK. Interesting that we have the same black screen problem with different norms and different devices. Does your device supply an mpeg stream? Mplayer in pvr mode detects the mpeg stream. It would be interesting to compare notes as we both try to figure this out...
