...and the magic happens, once all the drivers are supported for that computer.....
Just a note to update on my progress. I decided 1004 would not work for me because I needed mythtv 0.25 minimum for the HDHR3-CC and LMCE 1004 was less than that as I recall.
I tried mythbuntu 12.04.3 with mythtv 0.25. I was able to record some HD and SD content on the basic channels from Cox Omaha then I went wild in an effort to run a remote frontend from my laptop with the Mythbuntu LiveCD. As the mythtv setup reflected backend address of 127.0.0.1 I set out to change it to a "real" IP address.
Now I'm stuck where I can't launch the backend, the frontend, the backend gui or the frontend gui. I may have to reinstall it, which is probably timely, as I think now is the time to arrange for some storage.
I'm not really asking a question, but certainly will not refuse any suggestions anyone has for how to reconfigure my backcnd and frontend so I can "see" them again. Thanks.
