2004 Breaks My TV Tuner
I've tried twice to install build 2004 on my Core i7 HP Pavilion since
it finally became available. Each time it causes my Pinnacle HDTV Pro Stick 800e USB TV tuner to produce unwatchably choppy video and audio. I KNOW something 2004 is doing is causing it because I've tried installing another PVR software product (NextPVR as opposed to SichboPVR) and get the same results. I tried updating the video drivers and running sfc /scannow and neither of those helped either. Rolling back to 1909 gets it working perfectly again. Well, I was able to live perfectly happily without 2004 up to now but if anyone out there has any other ideas I'm all ears. |

You can also use Sysinternals Process Monitor, and see the what pile of things are flying around on the machine. The nice thing about modern TV signals, is that the digital packets are already compressed, and can be written to disk directly. If not watching TV, it's easy for the computer to deal with. The video card can also have a DXVA2 decoder for the packet and allow display with almost no CPU work at all. In Task Manager, in the GPU tab, you might see a little activity in there, representing the GPU contribution to viewing an image. It's possible to require more CPU, such as if you don't have a video card driver installed, and the Microsoft Basic Display Adapter is being used. There's be no GPU section in Task Manager. Decoding would be with the CPU. None of this would cause a Core i7 to rail, as it should have enough horsepower for this. If the image needs to be resized to full screen, and video card acceleration was completely broken, rescaling with a CPU takes more compute power. Have a look in Device Manager and make sure all the drivers are installed. My TV Tuner is one hardware device, which Windows 10 does not load automatically. Apparently Hauppauge didn't send a driver to MSFT. On Linux, I have to install the firmware manually, as it is not in the Repository tree. You should be able to sniff around and learn more about what is going on. Paul |
