That is usually related to a bad or old HDMI cable.
Edit, it could also be your Mirabox needs a powered connection. I use one of these on my capture cards to power them separately from the USB port and it helps a lot.
Why not try an Osprey box?
It's basically a cable box but for DirecTV Stream.
Spectrum works well on CHDVR with my AppleTV 4k with the exception of the DRM channels. I can use the Spectrum app on my AppleTv as well, but I already pay Spectrum too much now each month. They extort their customers with all the add on costs for locals channels, dvr service, set top box rental, etc.I pay nearlly $60 per month for their add on's. I could switch to Directv and save that $60, if my wife would agree.
Well, what you could do honestly is those boxes are like a good $50 from Walmart second hand.
They function basically like a cable box. You get a remote with channel numbers and buttons and a guide in the DVR. It basically looks like streaming cable TV. I would say do like a trial and maybe pick up one of those boxes from Walmart where you can easily return it just know that when you get the box from Walmart the remotes are usually kind of junky they sell replacement remotes on Amazon for literally $15.00 that are really nice new and clean.
Your wife would probably be happy with that because it really is just like a cable box. Then you would be able to feed channels with a Directv app and any ADB related tuning application. AH4C this, ADB tuner.
Improvements for local USB capture cards in v5.0.7:
- Deinterlace Mode Menu: Added a dropdown to fix camera jiggle.
- Smart Graphics Processing: Automatically uses your PC's graphics card for better performance.
- Smoother Video: Locked the framerate for fluid action scenes.
- Data Spike Protection: Mitigates network crashes during heavy action scenes.
- Color Correction: Fixed overly bright reds for more natural-looking colors.
- Memory Boost: Helps with dropped frames by adding temporary storage.
- Freeze Prevention: Added a shock absorber to handle minor WiFi hiccups without crashing.
I tested the 2 Capture Cards from Amazon. While they are both better than the $8 dongles, the Cenmate is far superior in picture quality. It is close to LinkPi quality. I will continue testing and recording on the two to verify. Neither has had issues with heat since they are bigger and dissipate it better than the smaller ones.
This is really a genius idea just get a PC with a bunch of USB ports and have at it I love it.
The LinkPi encoders are quite expensive and really need to be imported from China, so this is really great for people who just want to get into channels quickly without such an investment.
While I have way too many LinkPies, really a link pile. I do really think this is amazing work, so thank you for contributing it.
