Comment 23 for bug 659348

For the record, I've had some level of success by upgrading to the current Natty dev build. The steps involved were:

- Run command: update-manager -d
- Click the upgrade button and perform the full upgrade
- Installed the proprietary NVidia driver for my video card (I guess YMMV)
- Undo all the previous hacks I had used to try to get this going, including:
-- I had a /lib/firmware/xc3028-v27.fw file which I previously extracted from somewhere else. I removed that file and installed the firmware via the command: sudo apt-get install linux-firmware-non-free
-- I made sure I did NOT have cx23885 listed in my /etc/modprobe.d/blacklist.conf as an artifact from previous attempts to get this working
-- I removed the line 'modprobe cx23885 card=11' from my /etc/rc.local file
- Restart

I now have Mythbox finding all channels and able to view live TV and record. As a bonus I'm also able for the first time ever to use VDPAU for playback so it's clearer than it's ever been :) (perhaps similar to what Michael Cook is reporting).

Obviously Natty is a moving target right now so YYMV, but at least at the moment it seems to be something worth trying if like me your only alternative is an unusable Mythbox.
