Cowbutt's MythTV Page

With an eye on power consumption, I went for a combined frontend/backend implementation. I tried a quick run through with a scratch machine that I was no longer using. Once I'd determined, it'd probably be up for the job, I bought components specially.

Hardware Specification

  • Intel Celeron 1.7GHz CPU
  • 512MB RAM (originally 256MB)
  • Gigabyte GA-8PE667 Ultra Motherboard (i845PE)
  • Seagate ST3500630A PATA 500GB disc (OS, database, recordings)
  • Seagate ST3300622A PATA 300GB disc (originally only disc; now music, emulator ROMs)
  • LiteOn/JLMS XJ-HD165H DVD-ROM
  • NEC ND-4570A DVD+/-RW
  • Codegen ATX-9001 case
  • 1*Hauppauge Nova-T DVB-T tuner (originally 2)
  • 1*Hauppauge Nova-T-500 dual DVB-T tuner with Hauppauge infra-red remote control
  • 1*Pace Bt878 Analogue NICAM/FM tuner (not currently used)
  • 1*D-Link quad-port NIC
  • GeForce4 MX 440 AGP 128MB fanless VGA card (bought used to replace failing cheaper nVidia card)
  • home-built VGA-to-RGB SCART adaptor with integrated audio in/out and composite from SCART
  • 2*PADIX/Rockfire PX-205 PSX-USB Bridge with two Logic-7 Playstation dual-shock gamepads
  • Ruwido/Chicony KB-9820 infra-red PS/2 keyboard/mousepad

Software Specification

  • Fedora Core 8 running 2.6.23.1-42.fc8 kernel and standard video4linux drivers
  • MythTV 20.2 from ATrpms
  • pdnsd caching DNS server
  • privoxy ad-filtering HTTP proxy
  • DHCP daemon
  • netfilter/iptables firewall
  • NTP server
  • nVidia 96.43.01 drivers from ATrpms
  • Xmame/Xmess 0.106, fceultra 0.98.12, VisualBoyAdvance 1.7.2, zsnes 1.52, dgen-sdl 1.23
  • dvb-usb-dib0700-1.10.fw firmware for Nova-T-500

# RgbPath is the location of the RGB database.  Note, this is the name of the

# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

#	Option	"Xleds"		"1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
#	Option	"XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
#	Option	"XkbModel"	"pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#	Option	"XkbModel"	"microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#	Option	"XkbLayout"	"de"
# or:
#	Option	"XkbLayout"	"de"
#	Option	"XkbVariant"	"nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#	Option	"XkbOptions"	"ctrl:swapcaps"
# Or if you just want both to be control, use:
#	Option	"XkbOptions"	"ctrl:nocaps"
