The HD-PVR is a device that connects between a set-top box (such a your cable tuner box) and your computer (HTPC). It uses component video and S/PDIF optical audio connectors.
Earlier this year, Hauppauge released drivers for Windows 7 Media Center that let you use the device as one of your tuners within media center. In the community these are often referred to as the ‘native drivers’ since they come from Hauppauge rather than DVBLink which provides another solution for this to work.
People have had various experiences getting these drivers working. For some people they are great and others have a bad experience. My opinion is that this has to do with the other things running on your HTPC including background processes and codec packs.
While we all can hope that this should “just work”, there are many variables involved which combine to make it hard. Here is how I have it working with success. Much of this has been learned by my own experiences and the helpful people over on The Green Button. Hopefully it will help others get up and running.
First, my system specs:
- Atom ION
- 2GB RAM
- Gigabit Ethernet
- Windows 7 32-bit
- Hauppauge 2250 Dual Tuner Card
- HD Homerun Dual Tuner
- HD-PVR using native drivers
- My set-top box is a Scientific Atlanta 4250HDC
Getting started: Set up your set-top box correctly
The first thing you need to do is lock your set-top box to output only one resolution. By default, my SA 4250HDC had several resolutions checked. I changed this to ONLY 720P. The HD-PVR doesn’t seem to like the resolutions to change when you change channels
Next, be sure your set-top box is set to output Dolby Digital audio.
I can’t tell you how to do this on all boxes but here is basically how it is done on the SA 4250 (hopefully this will be close for some of you with other boxes)
- Press the Settings button on your remote
- Under Quick Settings, select Devices – Audio:Digital Output
- Ensure Dolby Digital is selected
- Still in settings, scroll right to Display
- Go into Output Resolution and be sure to check only 1. On my box the dots on the left of the resolutions indicate which ones that will be used. I use 720P as progressive is best in my opinion. What ever you decide, choose either 720P or 1080i. Lock it in as only 1 so the box isn’t trying to switch depending on source.
Make sure Windows 7 is up to date
Run windows update (might as well)
There is a Windows 7 hotfix that is not part of windows update yet. The notes on it do not indicate that it would help in this case but in my opinion it is a must for Media Center. I really do think it helps with channel changing. You can get it here: New functionality and performance improvements for the Windows 7 graphics platform (http://bit.ly/fRjCsw)
Set up and install the HD-PVR
Tip: If you have Windows Media Center set to start automatically with Windows, you might want to change that option to off. The installation process may take a couple reboots so this will help speed things up and minimize problems. For reference, this setting is in Media Center under Tasks – Settings – General – Startup and Windows Behavior.
Download the installation package and installation instructions from the Media Center tab of HD-PVR Support (http://bit.ly/ag73Cn)
Note: You do not need all the Arcsoft software provided with your HD-PVR for this to work.
Run the component cables and optical audio from you set-top to the HD-PVR input jacks.
Follow the instructions to install the HD-PVR down to the part about installing and setting up the IR utility.
Now, before you go on, take the time to make sure your HD-PVR is completely isolated from your other USB devices. 1Geek1Tool provides great instructions on How to isolate your HD-PVR (http://bit.ly/f4NdiH).
Once you have finished that process and your HD-PVR is on its own physical USB controller continue with the HD-PVR setup instructions to set up the IR software and the the MCE Installer.
The HD-PVR is considered a Digital Cable tuner when using the native drivers so you can easily install it along side your ATSC and QAM tuners.
After the tuners are set up in Media Center, disable background scanning to help improve performance:
- Open up REGEDIT and go to
- [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Service\BackgroundScanner]
- Create a new DWORD value, and name it PeriodicScanEnabled and set the ValueData to 0
- Close Regedit, and reboot the box.
Note: Don’t forget to enable the switch to start Media Center with windows if you disabled it in the tip above.
GuideTool is a handy tool for quickly editing your channel list (useful whether you use the HD-PVR or not). You can find it here: http://bit.ly/hBaw60.
Some people experience what is often called the Dual Tuner or Double Vision bug. This is where though you have only one HD-PVR showing up as 2 digital tuners. Fortunately, Mikinho of Missing Remote and The Green Button has written a piece of software that makes it easy to do a quick reset so only 1 tuner shows up. You can get it on Missing Remote here: http://bit.ly/hlN1Hj (note: you have to log in to see the attachment.)
Channel changing notes
The above instructions get you up and running with the HD-PVR’s built in IR port. Some people have issues with the built in IR blaster being causing long times changing channels. Here are some notes I’ve gathered:
How to increase the video bitrate and turn off the blue ‘bling’ LEDs
There isn’t a nice user interface method of change things like bitrate or that bright blue “bling” light. To do that you need a utility like GraphStudio. This isn’t hard, it just takes a few steps.
- Download GraphStudio http://bit.ly/goE0aa
- Ensure your HD-PVR isn’t recording a show then shut down Media Center
- Run GraphStudio
- Click Graph – Insert Filter
- In the filter chooser dropdown, scroll down and click on WDM Streaming Encoder Devices
- Select the Hauppauge HD-PVR Encoder in the left pane then click the Property Page button.
- Click the Hauppauge H264 Encoder tab
- Here you can change the Bitrate from its default 8 to 13.5 Mbps. You can also check the “Disable bling LEDs” box
- Be sure to click the Apply button after any changes
- That’s it! Simply close GraphStudio, start Media Center back up and enjoy some TV.
- Note, there are also some settings for Luma and Chroma. I didn’t change these. If anyone has changed them in a way they think increases picture quality, I’d like to hear about the results.
- The HD-PVR can take a lot of processing power. I suggest not running background processes such as Show Analyzer if possible. If you are having trouble and you must run these processes, at least try turning them off for a bit as a trouble shooting method.
