Fred,
You should send mail to the linux-media list; the video4linux list is mostly dead.
Analog support in the cx23885 driver is not complete. You can contact Steve Toth at kernellabs, if your company needs something in a certain timeframe and is willing to sponsor getting the functionality you need.
Also the CX23888 itself doesn't do MPEG compression. You'll need a connected CX23417 (or CX23416) to do the compression. (Maybe you have that, but you didn't mention it.)
Regards,
Andy
