Hi scram69

Thanks for your help. In my case it seems I'm using ivtv version 1.1.0 also,
as I saw with dmesg output:

administrator at media-server:/var/log/apt$ dmesg |grep ivtv
[   26.707822] ivtv:  Start initialization, version 1.1.0

I don't know exactly what was changed, because it was working very well
after the installation and now it never works. I will try to remove and
re-add the TV card to see if it has some impact on this problem

Best regards

Fernando
