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.

I haven't gotten the remote on the 2250 working. I was using a corded keyboard for a while, which was a pain. I've since enabled the [[Frontend control socket]] and I'm using the [http://code.google.com/p/mythmote/ mythmote] app on my Android phone as a remote.

* 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

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!
 
* [http://www.wilson-stowe.com/mythtv-information/mythtv-installation-guides/mythtv-installation-guide-for-debian.html MythTV Installation Guide for Debian] helpful for some Debian specific stuff, but not as good as I was expecting.
 
* [http://www-isl.mach.uni-karlsruhe.de/~hi93/myth/mythtv_debian_epia_pvr350_walkthrough Another Debian Guide] once again useful for Debian specific. the guide is down. email me if you want a copy...it is outdated.
 
* [http://wilsonet.com/mythtv/ 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.

My current rig came from newegg for about $600

  • Zotac Mini-ITX motherboard with NVIDIA GeForce 9000 and HDMI out (GF9300-K-E)
  • Intel Pentium dual-core 3.2 GHz CPU (E6700 Wolfdale)
  • 4 GB (2 x 2GB) RAM
  • 2 TB Hitachi Deskstar hard drive (HDS722020ALA330)
  • Micro ATX case, power supply, fan
  • Hauppauge dual TV tuner (WinTV-HVR-2250)

The system is running ubuntu.

I schedule all of my programs through mythweb.

I haven't gotten the remote on the 2250 working. I was using a corded keyboard for a while, which was a pain. I've since enabled the Frontend control socket and I'm using the mythmote app on my Android phone as a remote.
