I've completed a prototype for an NTSC decoder blockset for gnu radio. It's not very sophisticated but it lets you see video on the screen using gr-video-sdl. My development platform is Ubuntu 6.10 x86.

All I got was a black window. I know there is an analog TV station on the channel because my current work is using the USRP + fft to monitor the spectrum. When I display the FFT there is clearly a analog TV chanel with a 'classic' signature... i.e. clearly deliniated peaks for all signal elements, Video, Chomanence, and Audio.

What could be going wrong with my setup.
