Re: [PLUG] Building a MythTV setup

[TuskenTower <tuskentower@gmail.com>]

You have a good point.  I should mention my current network setup as
well as where the HDHomeRuns will go.  In connection order

Loft       -> HDTV Antenna and Cable connection
                  HDHomeRun + MythTV backend + 2 more computers
                  GigE Swtich ---------------------------------
                  Home Wireless Router                           \
                  Cable Modem                                           |

                |
Basement                                                                     /
                  Wireless Router #2 <----------------------
                  MythTV Frontend PC
                  HDTV

So, the intention is to have the backend connect directly to the
HDHomeRuns.  At the moment, only the Frontend will know about the
backend.  We don't have anything heavy duty running so only live TV
over MythTV could be problematic.

I'm hoping to not compress anything (aka I'll buy a 2-3 500GB disks)
since I have an HD set.  I was thinking of doing some upconversion as
a backend process (not sure if MythTV does that).  As far as I'm
concerned disk space is cheap.  Buying powerful processing units is
not cheap (purchase and energy costs).

What do you think?
