Zdravím. V debianech na architekruře amd64 se snažím rozchodit xdtv bohužel po spuštění z konzole se program sekne s chybou ioctl VIDIOC_DQBUF: Chyba vstupu/výstupu

celý proces spuštění:

This is xdtv 2.4.1cvs9 running on Linux/x86_64 (2.6.26-2-amd64).
scandir: není souborem ani adresářem
filename = /home/alex/.xdtv/xdtvrcioctl VIDIOC_DQBUF: Chyba vstupu/výstupu
/dev/video0 [v4l2]: ioctl VIDIOC_S_FBUF: Operation not permitted
v4l-conf: You should install me suid root, I need
          root priviliges for the VIDIOC_S_FBUF ioctl.
xdtv_v4l-conf had some trouble, trying to continue anyway
