[mythtv-users] xv support with Riva TNT2 card

[Chris Rickert]

[ We should move this to the mythtv-users mailing-list. ]

This is a common problem; the procedure that I've been suggesting:

        - patch < v4l2 patches > kernel-source
        - comment out the inclusion of time.h in
          kernel-source/include/linux/videodev2.h as per Isaac
        - cp kernel-source/include/linux/videodev*.h /usr/include/linux
        - build and reboot under new kernel
[0]     - update myth from cvs and build cleanly
        - update ivtv drivers from cvs and build
        - unload any previously-loaded v4l modules (specifically msp34xx)
        - follow ivtv/doc/capturing.txt to insert modules in proper order

Please let us know if this works for you so that it can eventually get
rolled into the Myth documentation.
