SageTV 9, Windows 10 and OpenDCT

SageTV is an awesome HTPC (Home Theater PC) software package. I've been running it for over 7 years now and it works great for us. It has just recently been updated slightly, mostly bug fixes and getting it up to date.  Here is how to do a clean install on a new machine.

SageTV version 9, wait what, I thought SageTV was dead? Yes and no, since being sold to Google all official developement has stopped.  However Google has decided to opensource it and the awesome people in the SageTV community have decided to update it.

My latest server build had been running flawlessly for over 4 years, I then had some hard drive corruption and even though I had backups the system was never the same afterwards.  About 6 months ago I rebuilt it on different hardware and it's been a mess ever since. I have decided to rebuild my old server with the newest software I could.  Here is brief explanation of the steps required to get you up and running with SageTV v9, Windows 10 and an open source cable card tuner called OpenDCT.

Task 1.  Install and Update OS
  1. Install OS of choice (For me it was Windows 10 Pro 64bit)
  2. Update the OS
  3. With Windows 10 it's very easy and quick.  I am loving Win10 so far.
Task 2. Install Pre-Requirements
  1. Install MS C++ 2010 Runtime (required for java 7)
  2. Install Java 7 32bit - This is super important, even if you have a 64bit OS, install the 32bit version of java 1,7.  Not 1.8 and not 64 bit.  This is a current limitation for several pieces of the SageTV puzzle. Developers are working on getting it updated.
  3. Install LAV drivers - required because Windows 10 doesn't include any Codec's
  4. Install drives for your network tuners.  Either Silicon Dust or Ceton are supported.
Task 3. Install SageTV 7.1.9
  1. Install SageTV 7.1.9
  2. If you need Cable card support you have 3 options.
    1. SageDCT - I've used this for years with no problems until recently. It's my understanding that it needs some updates and the creator just doesn't have the time to commit to it.
    2. PrimeNetEncoder - For SiliconDust HD Prime's - I tried it and had issues getting it to work
    3. OpenDCT - the latest opensource cable card tuner support solutions.  Installed with no issues and after a few tweaks is working great for me.
  3. I would suggest starting the SageTV Service first
  4. Open SageTV and configure it, add your tuners and channel line ups.
Task 4. Tweak some settings.

1. Increase java heap to 1gb - Since Sage uses Java, it needs more ram allocated to it.
  • click start
  • click run
  • type regedit and click ok
  • expand HKEY_LOCAL_MACHINE
  • expand SOFTWARE
  • expand Wow6432Node
  • expand Frey Technologies
  • under SageTV in right window doubleclick on JVMMaxHeapSizeMB
  • set as follows
  • 400 hexadecimal
2. Set your machine to reboot periodically. Due to memory leak issues, I set my machine to reboot every 3 days. Create a scheduled task to use shutdown.exe /r to reboot your machine.

Task 5. Test your setup
Verify you can tune channels and record shows

Task 6. Upgrade to SageTV v9
 1. See the SageTV 9 FAQ


I have been running this setup for several weeks now with no issues.  No corrupted recordings, no slow menus or anything.  Even though the future of SageTV is unknown, this system still works awesome for my family.

Why did you install SageTV V7 first as opposed to a clean install?
