The following is the documentation I used to configure MythTV on the following system:

Motherboard: Asus M3N78-EM
CPU: 65w AMD Athlon 64 X2 Dual Core Processor 5200+ Brisbane 2.7GHz
Heatsink/Fan: Thermaltake TR2-R1
RAM: 4GB RAM DDR2 800MHz Patriot
Video Card: On board video Geforce 8300
Sound Card: On board motherboard Realtek ALC1200 8 -Channel HD audio
HD: 2 x SATA 1TB WD Caviar Green WD10EADS-00L
Optical: Lite-On iHAS120 DVD-RAM
Remote: Harmony One Advanced Universal Remote
Tuner: HDHomeRun Home Networked Digital TV Tuner
Receiver: ONKYO TX-DS696
Case: Antec Fusion Remote Black
TV: Panasonic 42" plasma TH-42PX60U
Country: USA
TV provider: Comcast

This was done on the Mythbuntu 8.10 release by simply sticking the 64 Bit (x86_64) Direct Desktop Download CD in the drive and walking through the installation wizard. It was later upgraded to the Mythbuntu 9.04.

Configuring the HD Homrun Tuner:
* (time consuming) Channel mapping in Seattle required watching all the TV station, then hitting the 'E' key to type in the station information (Callsign and number) as per Plus enabling that channel in my lineup in
* Ensure that the network is up before mythtv backend (otherwise the tuner is marked as down)

LCD and Remote:
The new Soundgraph LCD/IR (Antec Fusion usb-id 15c2:0038 with RM200 remote) required the most custom work all phenomenally well documented on this thread

My 19 month son was helping and together we found we could move the front-end screen (by accident pressing the ctrl-[mouse right button[-drag). To restore reset here:

SPDIF(PCM/etc) Sound not working out of the box: For the builtin sound processor on the Asus M3N78-EM(Realtek ALC1200 8-Channel High Definition Audio Codec)
Requires adding the following line to /etc/modprobe.d/alsa-base.conf:
options snd-hda-intel model=6stack-dig

Secondly it required starting the alsamixer, scrolling to the right and un-muting the digital out (IEC958, IEC958 D, IEC958 1)
