Hello William, First of all, the video4linux-list has been moved to linux-media list at vger.kernel.org. The exact list address is linux-media@xxxxxxxxxxxxxxx and you can find other lists on http://vger.kernel.org. I removed the old list from CC and added the new list instead. I hope you don't mind. And about TVP5150 thing, I have been developing in similar way few years ago but in my case, I had a controller device which was video4linux device and took care of v4l2 ioctls in that controller and send command to i2c client. But in case of TVP5150, I can't figure it out which device could be that kind of controller device acting v4l2 device. I'm sorry about that and hope someone else (I think Mauro can) can answer this.
