Hello,

I am using a Hauppauge USB-Live 2 device to convert a composite video stream into USB so that I can display the video on the BeagleBone Black. So far, I have not had much luck. I have tried various video output formats, but the only one that seems to "work" is fbdev2. However, the only thing I see on my LCD is a green screen. I have searched several of the errors that are shown below, but have not turned up much so far. Does anyone have any suggestions on what I should try next?
