Hello Ron and All,
Ron, thank you for all of your work on your Ceton patch.
I reverted back to a fresh install of Mythbuntu 11.04 and applied your
patch. Everything is working well except live TV. I don't think it is your
patch's fault. It has been suggested that my problem was fixed in more
recent .24-fixes. This brings me back to trying to get you patch applied to
the latest Mythbuntu source. The repos that Mythbuntu uses to get
up-to-date .24-fixes builds are:
http://ppa.launchpad.net/mythbuntu/0.24/ubuntu natty main
http://ppa.launchpad.net/mythbuntu/testing/ubuntu natty main
I have found source code that seems correspond to my up-to-date frontend:
MythTV Version : v0.24.1-80-g1de0431
MythTV Branch : fixes/0.24
Network Protocol : 63
Library API : 0.24.20110505-1
QT Version : 4.7.2
I am not sure why the package manager knows how to pull up-to-date .24-fixes
binaries from these repos, but not source. I would expect the commands in
your tutorial to pull from this location as well, but they do not. Do I
need to add or modify repos in the package manager? Any ideas?
