Have you tried using v4l2-ctl to set the input?  That program usually 
comes with ivtv-tools (or a similarly named package on your distro).  
That's what I use to control the input source on my Asus PVR-450 which 
also has a cx88 chipset.  I'm doing captures directly from the mpeg 
encoder using `cat /dev/video0 > myvideo.mpg`, but I think it should 
still apply to using ffmpeg as well.
