MythTV is awesome for my roommates and I. We love the commercial skip! While I always hoped to experiment with MythTV, my roommates endorsed the idea in November 2006. My experiment has become quite a practical establishment in our house.
- Cheap Mini-ITX black case from Directron
- VIA EPIA 5000 Mini-ITX motherboard
- 512MB SDRAM
- 160GB Western Digital 7200rpm Hard Drive
- Hauppauge WinTV-PVR-350 Tuner Card
- Debian Etch
- Kernel v2.6.18-3-486
- X.org v7.1.1
- IceWM window manager v1.2
- ivtv drivers v0.8.2, firmware v184.108.40.20668
- lirc version v0.8.0
- MythTV v0.20.20060828-3
What's working for me
- XV on PVR-350
- Live TV/TV recording
- TV Listings from Zap2it
- Windows Watching Recordings in Windows with MythTv Player
- Using irexec to restart Myth when something goes wrong
- myth2ipod with modifications
- MythFrontEnd with X-Forwarding via Cygwin
I tried quite a few distros before figuring out how to upgrade Debian to Etch. Here's what I can remember that conflicted with my setup, mainly the EPIA motherboard. See the Operating system page for more distros and information.
I think I tried some more, but ran into some other probelms.
- Fedora: trouble burning and then installing. I might have been lazy.
- AMICUS: I looked into, can't remember why i didn't use it.
- PlutoHome: I think it conflicted with EPIA. Also might have been a little heavy for my 500Mhz processor.
On-Screen Program Guide
The On-Screen Electronic Program Guide stopped working for me at some point. The focus seemed to be screwed up. To get Myth working again, I had two options: restart or telnet. the telnet option required a
killall mythfrontend ivtvfbctl /dev/fb0 --globalalpha off --localalpha off mythfrontend &
I haven't spent much time diagnosing the problem though. when watching LiveTV I use comcast's digital cable EPG. I use MythWeb to schedule my recordings. Any suggestions are certainly welcome, though!
I used many resources to help me with the installation. I pieced the story together myself, without following one set of directions and having it work. here's what I used, in no particular order.
- This Wiki!
- MythTV Installation Guide for Debian helpful for some Debian specific stuff, but not as good as I was expecting.
- Another Debian Guide once again useful for Debian specific. the guide is down. email me if you want a copy...it is outdated.
- Jarod's Guide great for WinTV-PVR info and other mythtv concerns. biggest difference is using apt instead of yum.
The PVR-350 is awesome for this puny system. Before I had tested the hardware mpeg-2 decoder, I tried playing a recorded mpeg-2. the video was very, very, very choppy and slow. I was a little worried that I may have spent money on a useless machine. The reviews on the hardware decoder lived up to everything the should have, though. I am able to record a show, commercial flag two shows, and watch a recording without noticing anything.
Switching to IceWM was a big help on cutting down system overhead. Login time decreased a considerable amount.
MythWeb is pretty darn slow. Searching and TV listings especially.
I'd Love to see MythWeb transcode files after recording
I don't have any updates/modifications planned.
Useful config info

(Re)-Start Myth Frontend
startmythfrontend script to restart MythTV via irexec.
#!/bin/bash # (Re-)starts mythfrontend # This script gets executed when the "Go" button on the remote is pressed # # Torsten Schenkel, edited by Matt Burke # Reset the alpha values for ivtv-fb so we can see the X desktop (not always done automatically) ivtvfbctl /dev/fb0 --globalalpha off --localalpha off # Kill and start mythfrontend killall mythfrontend # Restart mythfrontend echo "`date` RESTART" >> /home/mythtv/mythfrontend.log export DISPLAY=:0.0 mythfrontend >> /home/mythtv/mythfrontend.log &
the .lircrc file (buttons as per the DVICO remote, which I think are now standard in the lirc distribution)
## irexec begin prog = irexec button = GO config = sudo -u mythtv /home/mythtv/bin/startmythfrontend & end
I was getting a floating point exception from ffmpeg. the Nuvexport - Bug Fix details the fix i used.
