I was keeping track of where I was at with Myth on my home wiki, but then figured I might as well share it here!
Major update in progress - split frontend/backend and using later versions of ubuntu/mythbuntu
My Setup
MythBuntu 8.10 with separated front-end/backend
- Live TV/TV recording Free to air HD/SD (from Sydney, Australia)
- Multi-rec
- DTS/AC3 passthrough including 5,1 surround digital out
- MythMusic
- MythGallery
Backend
Hardware
- 2 x 500GB HDDs
- Intel S775 Core 2 Q6600 Quad-Core CPU
- Gigabyte S775 GA-G33M-S2 Motherboard
- 4GB RAM
- DNTVLive LP Tuner
- PCI Hauppauge Nova-T-500 MCE(OEM) Dual DVBT tuner
Software
- Ubuntu 8.10 64bit
- MythWeb on Jetty rather than apache including the WAP version on the BlackBerry!
- Shepherd XMLTV grabber
- NFS server for music/images
Configuration
- DVICO used device id 17de:a8a6 for two distinct devices requiring different drivers. Need to set "options cx88xx card=19" in /etc/modprobe.d to force use of Conexant reference drivers. Fortunately the Hauppauge tuner is a USB device so we can override the autodetection rather than patch the v4l dvb drivers to override it.
Frontend / Slave Backend
Hardware
- AMD S754 Athlon 64 3700+
- Gigabyte S754 GA-K8VM800M
- 1GB Ram
- 320GB Western Digital 7200rpm 8M Serial ATA HDD
-
Albatron FX5200LP 128M 8x Video Card with DVI output. - Gigabyte FX5200 128M 8x Video Card with DVI output.
- DVICO FusionHDTV Hybrid Tuner
- DVICO FusionRemote MCE
- BenQ PE8700 DLP Projector
- Samsung LCD Television
- CambridgeAudio AV receiver
Software
- MythBuntu 8.10 64bit
- [[1]] to allow laptop to be the keyboard/mouse.
Configuration
- cx88_dvb in /etc/modules (needs to start early to load properly, not sure why)
- disabled GDM in favour of a simple mingetty startup
- user .xsession linked to /usr/share/mythbuntu/session.sh so we get the same xfce startup.
- autostart irexec to restart MythTV and switch xorg layout between the Projector and TV
/etc/lircd/hardware.conf
Default chooser from mythbuntu did not find the usb device at /dev/usb/hiddev0, so need to edit this file explicitly.
#Chosen Remote Control REMOTE="DVICO_MCE" REMOTE_MODULES="" REMOTE_DRIVER="dvico" REMOTE_DEVICE="/dev/usb/hiddev0" REMOTE_LIRCD_CONF="/usr/share/lirc/dvico/lircd.conf.fusionHDTV" REMOTE_LIRCD_ARGS=""
xorg.conf for PE8700, Samsung LCD. See also the tips for the NVidiaProprietaryDriver
The FX5200 cards were the cause of my DVI problems on my projector. Apparently they freaks out a PCB component causing the EDID data to become corrupt. (the Gigabyte card lasted from Aug 2006 to Dec 2007. Fortunately the new nvidia driver allow you to use a CustomEDID to load the data from a file.
Option ExactModeTimingsDVI is important for the projector.
Option "UseEDIDDpi" "false" or some equivalent control of DPI is important for the Samsung television otherwise you get really small fonts (fixed in 0.21)
There are two layouts, the default uses outputs via VGA to a Samsung LCD television, the second uses DVI to the PE8700 projector.
