I have a Hauppauge HVR-1250. Now on a Pentium 4 3.06Ghz machine Kodi 17 rc4 on Windows 7 32bit.
I have had similar results on Windows 10 and Ubuntu 14.04 LTS.
Similar results whether I'm using NextPVR, SWMC, or TVheadend.
Similar results whether the receiver is on the same machine as Kodi or on another.
Similar results on earlier versions of Kodi back to 15.

When I watch Live TV on WinTV7 or 8, WMC, NextPVR or TVheadend no stuttering or buffering or sound sync problems.

When I watch Live TV on Kodi the best case is SWMC where the images look like "computer" videos (skipping frames) and the sound is just a bit out of sync, but with buffering.

With NextPVR I tried all of the filters.

I am getting tired of changing computers and OSs. I seem to be the only one with the problem. Are there any adjustments to Kodi that I'm missing?

Since the problem is not specific to swmc. I think it would be better to post on the forum above this one.

Its not clear to me what the machine is that is running kodi, but since you have tried so much stuff, I assume you have this problem even when kodi is running on the same machine as serverwmc, right?

Do you have any of these problems when watching recordings in kodi?

I'm not sure what 'computer' videos means exactly. Do you have deinterlacing turned on in kodi? Have you tried turning off hardware acceleration in kodi's settings?

Right now SWMC and Kodi are on the same machine.

The same thing went on when I had them on different machines, I assumed it was a network problem.

"computer" video means losing every 20th or so frame. Kind of like stop-action. Like trying to watch TV on a computer with a 8086 or a old cellphone. Like runners appear to be dragging their toes.

I just checked again Kodi 17 rc4 does not have any settings for acceleration or interlacing. But yes, I had tried that in earlier Kodi versions.

I did a 1 minute test record. It looked just like the live.

Next I'd try opening this recorded tv file directly (bypassing the pvr interface) and see if the problem persists in kodi. Assuming it does, then I agree with you that it sounds like its a kodi issue, why others don't see it is a mystery to me too. If you move it to a different machine and still have the same problem in kodi, then I'd submit the file to the kodi team. I'd also be willing to look at it, just to see if I see anything on my system. You can upload it to here if you want:

I fixed it, I had to find the interlacing setting in Kodi.
