freebsd-ports/mbone/vic/files/patch-af
Bill Fenner 0b7a232ad3 Fix Luigi's recently committed submission: 
- Actually include the x11 grabber in the compile
- Don't force the capture type to PAL; leave it at auto
- Remove debugging code and comments
- Eliminate the need for kernel patch for tuner code
- Don't patch one source file in more than one patch-XX files
