Introduction

Welcome, intrepid media-center adventurer! You’ve heard of MythTV, the venerable DVR powerhouse, and you’ve heard whispers of LinHES (formerly KnoppMyth) making the installation a breeze. Buckle up your HDMI cables, pour yourself a mug of coffee (or tea, if you’re feeling posh), and let’s transform that humble PC into a mythical home theater beast—without burning the house down.

Why LinHES?

• All-in-one package: MythTV, codecs, device drivers, front-ends—pre-configured!
• Minimal fuss: Just follow prompts, and LinHES does the heavy lifting.
• Active community: Friendly forum at forums.linhes.org.

Prerequisites and Hardware Requirements

Before you march onward, ensure your gear is up to snuff. Here’s a basic shopping list:

Pro tip: An SSD boot drive and a spinning HDD for storage is the best of both worlds.

Step 1: Download the LinHES ISO

1. Open your browser and navigate to LinHES official site.
2. Click “Downloads” and choose the latest stable release ISO (e.g. LinHES 9.0 or above).
3. Save the ISO to a safe folder on your desktop.

Step 2: Verify the ISO (Optional but Wise)

Make sure your download isn’t corrupted:

# cd ~/Downloads
# sha256sum LinHES-9.0.iso
  

Compare the checksum output with the one on the download page.

Step 3: Create a Bootable USB

Two popular ways:

Method A: Using dd (Linux/macOS)

# sudo dd if=LinHES-9.0.iso of=/dev/sdX bs=4M status=progress  sync
  

Replace /dev/sdX with your USB device. Triple-check or you might wipe your main disk!

Method B: Using Ventoy (Windows/Linux/macOS)

• Download Ventoy from ventoy.net.
• Install Ventoy to your USB stick.
• Copy LinHES ISO onto the Ventoy partition—no re-flashing needed!

Step 4: BIOS/UEFI Configuration

1. Reboot and hit F2, Del or manufacturer’s key to enter BIOS.
2. Enable AHCI for SATA controllers (if available).
3. Disable Fast Boot and Secure Boot (LinHES isn’t signed for Secure Boot).
4. Set USB as the first boot device.
5. Save amp Exit.

Step 5: Installation Wizard

Once you boot from USB, you’ll see a friendly text-based installer:

1. Select your language (English, Español, Klingon, etc.).
2. Choose “Install LinHES” (not “Upgrade”).
3. Partitioning options:
   • Auto: LinHES will create root (/), swap, and /recordings partitions.
   • Manual: Advanced users can tweak LVM, RAID, or custom layouts.
4. Confirm your timezone and keyboard layout.
5. Set a strong root password and a MythTV-enabled user.
6. Choose network configuration: DHCP or static IP.
7. Point to an NTP server for time synchronization.
8. Kick back while the installer partitions, formats, and installs the OS. This can take 10–20 minutes.

Step 6: Reboot and Initial Setup

1. Eject the USB when prompted, then reboot.
2. Log in as root or your user to confirm everything looks healthy.
3. Run the built-in LinHES Setup Wizard by typing setup in a console.

LinHES Setup Wizard Highlights

• Kernel Modules: Select drivers for your tuner cards (DVB, HDHomeRun, etc.).
• MythTV Screen Setup: Test your video output—HDMI, DVI, or good old VGA.
• Audio Configuration: Choose audio card and test sound.
• Database: Local MySQL or use a remote database server.
• EPG Data: Configure XMLTV grabbers or use a cablecard guide importer.

Step 7: MythTV Frontend Backend

LinHES integrates both:

• Backend: Handles recordings, storage, EPG, transcoding.
• Frontend: User interface for watching live TV, recordings, and streaming.

Typically, your server will run the backend, and any networked device (another LinHES, Raspberry Pi, HTPC) can run the frontend.

Step 8: Post-Install Tweaks

1. Update your system:

   # yum update -y

2. Install additional codecs if needed:

   # yum install ffmpeg x264 x265 libvdpau

3. Enable remote access via SSH:

   # systemctl enable sshd  systemctl start sshd

4. Configure backups of your recordings directory to an external drive or NAS.

Troubleshooting amp Tips

• No tuner detected? Run lsusb or lspci and ensure the correct kernel module is loaded (modprobe dvb_usb_v2, etc.).
• EPG not populating? Check cron jobs in /etc/cron.d/mythtv and review /var/log/mythtv/epgGrabLog.txt.
• Blacklist PulseAudio: MythTV prefers ALSA. Add blacklist snd_pulse to /etc/modprobe.d/blacklist.conf.
• Frontend stutters: Adjust vsync and video sync settings in Main Menu → Setup → Video.

Wrapping Up

Congratulations! You’ve just performed a ritualistic installation worthy of the ancients, summoning forth a fully functional MythTV environment. Kick back, grab the remote, and start recording your favorite shows—and maybe even a documentary on medieval cheese rolling. If you run into bumps on the road, the LinHES forums and MythTV Wiki are your trusty sidekicks.

Remember: TV may come and go, but your home theater glory remains eternal!
