With a little tinkering i got rid of the forcecc error by changing one 
line in the cx23885-video.c,  while keeping the video as it is...

diff -r cx23885-video.c cx23885-video.bak
148c148
<         .depth    = 16,
---
 >         .depth    = 32,


Still same old static picture on the video (refer to uploaded video 
earlier post). Hangs while changing channels. Still getting the firmware 
errors.

Well, I've blacklisted the module, I'm tired of fooling with it, and not
getting any help. Guess it's a $140 paper weight till sometimes gets time or
cares.
