[mythtv-users] Two lingering issues with 0.20 and/or Ubuntu

[Michael Tiller]

Mario,

  Thanks for the response.  I did not use mythtv as my first user.  In fact,
I used your guide <https://wiki.ubuntu.com/Install_IVTV_Edgy> (which I think
is quite good) which is how I knew not to do this. :-)

  Note that I have no trouble starting it manually (via sudo).  I have added
three lines which I've highlighted in red.  When I get home I'll try taking
them out and see if they make a difference but if the script is run as root
I can't see why it would make a difference.

  I dont know what the lines:
# Default-Start:     24
# Default-Stop:      S
...mean but I'm assuming they are fine as configured.

  Note that everything in red is a hack so I'm working on trying to
eliminate the need for them.  I know that somehow udev is responsible for
the permissions on ttyS0 but I have yet to figure out how to specify a rule
so it gets the permissions right.  The other two things Myth should do for
me but does not seem to?!?

  Thanks for any ideas.
