Before building my MythTV box, I surfed a lot to find some help. And it did help me. In case you are thinking about building your own, these links might be interesting to check out.

Hardware:

• Setup PVR 500 for MythTV with KnopMyth
• Slim on MythTV (google's cache). MythTV's built in music player is fine but not nearly as good as the Slim Devices system. Like MythTV, Slim uses a server/client(s) architecture. Slim's server is an open source marvel that has just graduated to version six and has a bunch of great plugins that do everything from reading RSS to listening to the Internet Archive's great collection of concert and other free recordings. It's clients range from slim's own fabulous hardware versions to the open source software version called SoftSqueeze (because slim's new hardware players have been called Squeezeboxes). Can't say enough good things about slim devices and wanted to use SoftSqueeze on my KnoppMyth-based MythTV. Here I'll explain how to get that done.
• LIRC Driver for MCE 2005 remotes, This driver is designed as a plug-in replacement for the existing MCE driver.
• SlientPCReview.com, Silent PC Review is dedicated to reviews, news and information about quiet, low noise, noise-free and/or silent computers and components.

Remote2Key, allows you to control your computer with a remote control.

• Lots of information about Win PVR 500

Software:

• Wiki at MythTV.org, he information and documentation wiki for MythTV.
• Knoppmyth, KnoppMyth is my attempt at making the Linux and MythTV installation as trivial as possible. Think Knoppix meets MythTV
• MythTV Architecture, Over the last couple years MythTV has grown into a rather large application. The purpose of these pages is to provide a portal into the code for developers to get their heads around it. This is intended for both those new to MythTV and experienced with it to get familiar with different aspects of the code base.
• WinMyth, using your windows machine as a frontend for watching TV. Note that a TV stream needs lots of bandwith and with most Wifi "B" connections going up to 3 or 4 Mb IRL, not something you might want to do. Having 802.11G or Fastethernet will make it work
• Head code of MYthTV, it was CVS but they turned towards Trac
• LinPVR.com, dedicated Linux distro called "MiniMyth".

MythTV Plugins:

• Official Modules of MythTV in core as well as a dozen contributed mocules
• streamtuned, plays and records audio and video streams using mplayer as backend. Also Streamsnif, a command line tool that sniffs network traffic for stream url's.
• MythTV Retro theme, a very good looking retro theme
• Project Grayhem is a user interface theme for MythTV. I dodnt think it is very nice but taste is something to debate about.
• MythExtra, MythTV Modules for Radio, Recipes, Mail and Karaoke

Howto's:

• MythTV install, from the MythTV site
• Do It Yourself PVR Wiki, Besides being a tongue twister and a pain of an URL to type in, the DIY PVR DVR HTPC Wiki (DPDHW ?!) is meant to be a community grown documentation / Frequently Asked Question (FAQ) project.
• Build your own PVR, mus read. This is a community driven discussion for building your own PVR / DVR / HTPC (think Tivo without a recurring $ub$cription). Anything from mini-itx, case modding, which video card, to which software package is most advanced is fair game.

A beginner look at MythTV, MythTV is a software package that lets you turn your Linux-based computer into a television and personal video recorder (PVR) by recording shows onto the hard disk.

• Build Your Own Linux Home Theater PC, o, before you embark on trying to build a Linux-based Home Theater PC (HTPC), you have to ask yourself a question: "How much time do I have to dedicate to bringing up a Linux-based HTPC?" If the answer is "not much," then a Linux-based HTPC is probably not something you should build.
• The PVR Guide, PVR stands for 'personal video recorder'. This is a piece of computer software that allows you to record TV programs.
  This really doesn't do justice to the programs that exist today. It would be better to describe them as multimedia centres than to call them recorders. They now also allow you to play games, watch picture slide shows, listen to music and much more. It has become almost everything you need (excluding the TV of course).
• Wiki on Linuxtv.org
• Lots of install guides, "The following links and pages are installation guides written by users who have built their own PVR."
• Howto install aMytTV frontend
• MythTV easy howto for Ubuntu

Misc:

• plutohome.com, some very nice hardware for home automation control. Not directly PVR/MythTV related, but can be the icing on the cake.
• MythTV at wikipedia, MythTV is a GPL open source application for Linux designed to allow any computer (that meets the specified minimum requirements) to function as a personal video recorder.
