Hi, Rod:

Sorry for late replying...

Following is my patch to v4l-dvb (v4l-dvb-4c4fd6b8755c)
The patch is mainly adapted from Newbigin's patch, but the case in saa7134_board_init2 is talltolly a nonsense guessing...    lol

Ask a newbie question...  lol
What's the role of I2C plays in between these chips?
