I _think_ the comment in the Wiki is a typo and should read export: MYTHTVDIR=<wherever mythtv is actually installed>
(or the readlink although I didn't test that).
You should see a line in the backend containing this: Using runtime prefix = <whatever is in $MYTHTVDIR>.
If I change the above to point to /usr/local (where it truly lives), my backend works. If I change it to
/tmp, I can duplicate the 404 errors.
Your 6755 screenshot looks right for the early development and you shouldn't use it for WebFrontend.
Sounds like MYTHCONFDIR is working as you want it to. If if the user that the backend runs as has a .mythtv directory
in its HOME, it's not required.
