Having an issue where hardware transcoding is not working, trying to play content does not load, however software transcoding does however. I have channels DVR running on a headless server with an i5 6500 with Intel HD Graphics 530. As I mentioned, it is headless, would this impede channels trying to transcode via hardware? I am running my Plex server on this machine as well, so would that be having an issue where it would not allow it to be used? I was looking in task manager on the computer and I saw igmpfx or something like that. Any ideas? EDIT: I should also mention that this is through the web GUI, just installed last night, donāt know if it works on ATV yet
Yes this might be why.
Please post what the Log says when you try hardware transcoding.
This is what the log says. All the web UI player says is āTranscoder startingā but does not ever play anything.

Looks like the hardware transcoder is failing to initialize.
Please plug something into the hdmi port and see if it makes any difference.
Also you can try to update your drivers to the latest version: www.intel.com/content/www/us/en/support/detect.html
Yeah, I tried updating to the latest drivers and it did no good, I will try out hooking up a monitor later today and testing. If that ends up working I might try to see if I can set up a virtual display to trick the driver into thinking there is a monitor attached.
Just tried hooking a monitor up to the PC and tried hardware transcoding, no luck.
Bummer. Did you try playing back a recording instead of live tv? Is that the same?
Note that you can still use software transcoding no problem (just like Plex does), and that watching from the Apple TV does not even require a transcoder.
Yeah software works great, I have not done a recording as of yet and playing that through the web interface, CPU is about 30% load using software at 1080p @10 mbps. Obviously ATV is more important than the web UI but find it odd that hardware transcoding does not work, I will just use software when I am out of the house and perhaps we will find a solution for hardware transcoding in the future, other than that so far it is working great!
Odd indeed.
I found someone else who was having this issues on windows10, and said:
The problem stopped occurring for me when I updated to the latest IntelĀ® Graphics Driver (version 15.45.10.4542). Hopefully this will work for others as well.
What version of the driver was installed after you updated?
Also earlier on this thread @facke02 reported getting the same error watching live tv. But watching recordings was working just fine.
Try making a quick recording on the web interface and see if it plays back.
@facke02 Are you still getting the encoding error on live tv?
Question on transcoder. I am on Windows 64 bit. I do not see hardware option on Web Player, only software. Software transcoder works fine, just curious about expected functionality.
What graphics card?
ATI Radeon HD 3470
At the moment we only support Intel HD Graphics and Nvidia for hardware transcoding.
Great, that explains it. There was probably some place I could have self served that info 
Again, no issues, just wanted to make sure it was working as expected.

I am having trouble downloading guide data to my Windows computer. I am connecting Fios cable to my HDHR connect for local channels as they are unencrypted. I have no trouble downloading guide for OTA channels but when I select Fios digital from Burlington it says it is downloading 156 channels and after a few minutes goes idle, but nothing shows up. This is for Boston, MA. Any help would be greatly appreciated. Thanks!
What are the channel numbers you get on the Connect with FIOS attached? You will probably need to select the Local Broadcast guide option so the channel numbers match up.
All of the locals come in fine and am able to watch live. I get several channels but the main ones being:
2.1 PBS
4.1 CBS
5.1 ABC
8.1 NBC
56.1 CW
By local broadcast guide option do you mean the OTA option?
Yes, you are getting OTA channel numbers so select the OTA guide source.
