So I suppose the card is recognized by the kernel and all drivers all loaded. I installed tvtime but no matter what I do the only output is a "no signal" label on blue screen. I checked the tv cable is plugged and when connected to a tv it showed a nice signal.

any idea ?
thanks for the help

I have the same AverMedia card I think and it works fine here. My guess is settings or permissions.

Did you configure the software to use the right device? For example, if you also have a webcam then it will usually be the default device /dev/video0 and the TV card will be /dev/video1.
