Revision as of 17:46, 4 August 2009

My Goal with this Wiki is to document the trials and tribulations of saving a few dollars on building a High Definition Capable MythTV system on a budget. This meant buying whatever I could at decent prices off of craigslist.

As part of keeping more of our paycheck (Thanks Dave Ramsey), we decided that we needed to get rid of DishTV. Out of the entire package, we felt that losing DVR functionality was unacceptable, so thus started our MythTV journey. Again, in the interest of budget, we found that building our own frontends with new hardware (intel atom boxes) would cost about 200-250. Therefore, I priced out some criagslist prices and found that I could save about 100-200 over the entire project by buying used computers. Since almost all of the MythTV documentation online talked about older hardware, it seemed like a great path.

Original Objectives:

  - Spend about 100 - 150 per frontend
  - All frontends should be able to handle HD TVs (current TVs are CRT, but you never know what Santa will bring)
  - Diskless would save some money, power and noise
  - Keep the total project at around 500, that is approx how much DishTV was costing us a year.


Backend: Total: $202

  - I had a home-built Athlon 3700 box collecting dust (yay for breaking WoW addiction)
  - Hauppauge WinTV-HVR-2250 tuner card - $112
  - 2G RAM
  - 160G HD
  - 1TB HD - 90

Frontend 1: Total: $135

  - Dell Optiplex 320 3.0GHz  - $80 from craigslist
  - ZOTAC ZT-94TEH2L-FDR-V1 GeForce 9400 GT 512MB  - $41 from newegg
  - 1G RAM - $14 from Frys
  - 80G HD
  - streamzap remote - $30 from amazon


Frontend 2: Total: $113.99

  - HP 2.6GHz - $80 from craigslist
  - ZOTAC ZT-62AA250-HSS GeForce 6200 256MB (AGP)  - $33.99 from newegg
  - 1G RAM
  - 80G HD
  - streamzap remote - $30 from amazon


Networking: Total: $218

  - Linksys Router - already owned
  - Linksys PLK300 PowerLine AV - $145 
  - Linksys PLE300 - $73 from amazon
  • Note* I tried a wireless card, SD channels showed up great, but the HD channels were horrible. This was a WirelessG card. Not sure how N would work. The powerline stuff is expensive, but it is working really well.

TV:

 - Terk Technology HDTVi antenna - $45 from Frys

Total Cost:

 $713.99 + some shipping not included above (could have probably saved a bit more by more craigslist shopping, but oh well)

Approx Savings from buying new hardware: (assuming $200 per frontend)

 $151.01
 

So there goes the budget :( It will take about a year and a half to start making money off of the setup.


Now, for the part you probably came here for, Getting Mythtv Working.


Backend: After some research, I found that mythbuntu was one of the more popular options in terms of forum and documentation support. So I installed a BE/FE configuration on my backend for testing. After looking at the eye candy and the features, I got preliminary wife support to go ahead with the project. So I ordered the Hauppage 2250 Tuner card. This brought up problem #1.

 Issue: Hauappage TV Tuner Card does not work in Linux out of the box
 Solution:  God liked me and gave Steven Toth the great wisdom to make drivers for it.

 NOTE:  Whenever you update the kernel image, you WILL have to re-compile this

After getting it to work, I got LiveTV! Everything was working great on my backend. Then I noticed something.

 Issue: HD recordings can take up to 6Gb/hour.  SD is about half of that.  
 Solution:  Auto-Transcode the kids shows.  Make sure to watch the adult shows quickly.  Decided not to auto-transcode the adult shows because we tend to watch them the same night.  When the shows build up, we may auto-transcode more of them.  Of course, we also ordered a 1TB HD :)   After transcoding, the kids shows take about 1G/30 minutes and adult shows about 3G/hour

So great, backend done, now for Frontend #1. After some craigslist lurking, bought a Dell Optiplex 320. Small, quiet, PCI-express slot, 3Ghz, perfect, right? Only after about 20ish hours of work! :(

  Issue: Dell Optiplex 320 Does not like booting linux.  Not sure on the details, but after some research found that it needs Grub2
  Solution:  Will have to link the website I found, but the jist of the solution is that you need to install Grub2.  This is not so easy with mythbuntu and requires some command line interaction.
  Solution #2: While working on Frontend2, I found Ubuntu Minimal Install ISO.  This requires a little bit of additional technical knowledge, but allows the option to install grub2 and mythbuntu from the install menus.  More details later.
  Issue: Dell Optiplex 320 Does not recognize USB ports until after the middle of loading the OS.  So diskless bootup went out the window since the machine would boot off the USB, but then I had to unplug it and plug it back in when the mythbuntu bar was about halfway across the screen. Painful.
  Solution:  Hard Drive install.  Tried network booting, but could not figure out how to manage the mythbuntu network boot features.  I could create the linux image, but updating it and maintaining it seemed painful.  Also, could not get network booting to work very well on the Dell.
  Issue: Wanted to use my existing DishTV remotes with the streamzap receiver. I will try to re-find and post the website that helped me with this.  The most important key that I learned is that hopefully you have the Dish remote that can learn.  So I took the streamzap and the dish and had the Dish remote learn all the streamzap codes.  That way, the streamzap receiver just though the Dish remote was the streamzap and from there, just got all the codes straightened out and mapped the way I want them.  Will include the file later.

So Frontend 1 is working great with the video card installed. Able to watch LiveTV, view movies I put on the backend, record things, working great. I learned enough about NFS to connect the movie directory ont he backend machine to the frontend machine so now all the frontends can share one video library. YAY. Now its time to disconnect it from the router :)

Purchased a wirelessG card. SD channels work great, but most of the channels now transmit HD over the air. So only like 2 channels worked. All of the other ones would play for a minute, stop, play another minute, stop, etc. All the stuff online said it worked, but that was written a long time ago and probably didnt cover HD. Let me tell you right now, even in the same room 10 feet away, WirelessG will NOT work for HD channels.

More research and advice from my c-worker (thanks Erik), I came across Ethernet over Powerline. While scary sounding (don't be messing with my power) and expensive, I was too far into the project to quit now. Sure enough, it worked great! From all the power outlets that I cared about, the bandwidth was plenty.

So Frontend 1 Was now live in a room across the house. After some testing and more diddling (thats the thing with MythTV, theres always room to tweak). I will try to cover some of the more important tweaks a little later.


Frontend 2: The bad part about craigslist is that you either have uber patience to find the price/item you want, or grab what you can take. So I bought a HP 2.6GHz. Again, from reading online, 2.6GHz was marginal, but should work. Mythbuntu stated recommended for HD was 3GHz, but I waited a week or so and couldnt find another Dell Optiplex 320 for a decent price.

Anyway, install went smoothly, mythbuntu Frontend.
