Feeding my ATIs s-video out into my digicams input makes every renderer turn grey. What does that mean?

TTY says:
00:01:47 * : a resource couldn’t be created because of the following reasons:
Alpha in texture pixels is not supported. Your texture format (A8R8G8B8) has alpha.

if you are using a DX9Texture try to change the texture format to a non-alpha format via inspektor. else it could be the backbuffer of the renderer. also see inspektor.
