That's why I asked for "low-grief". I wanted something that people
have already gotten to work the first time.

Which is definitely not the way to do it on the cheap. Also, I've
already tried running MythTV with a keyboard, and I found that some
menus just wouldn't work. I assumed that this was because these menus
wouldn't work with a keyboard, but they would once I got a decent remote.
Assuming everything you put is accurate, I wish I had found this
information when going through FAQs and the Wiki. Maybe it should be put
