Yeah, that's what I expected based on the information you provided, 
before.  So, at this point, you can feel free to un-apply that patch and 
use unmodified MythTV.

Based on this, I would suggest that it's likely your capture card 
configuration is broken due to upgrades to kernel and driver.  You 
should do the capture card (not the video source) portion of: 
http://www.gossamer-threads.com/lists/mythtv/users/264034#264034 (the 
"If you ever change capture cards or capture card drivers..." paragraph).
