My setup is running on Lubuntu 18.04
Kodi seems to work fine for streaming.  I can connect to Mythtv backend without issues.  The problem is playback of OTA recorded TV, it is choppy and lags.  I have combined Mythtv backend and Kodi into a single pc (so it connects to itself).  The storage is also local.  If I connect to Mythtv backend from another Kodi machine such as my Raspi 3, the playback works as expected.  The problem seems to be isolated to just my combo pc. 

I want to know if my setup can be fixed/optimized or should I look at getting something newer?
I'll be the first to admit the computer I have is rather old even for use with Linux. It has 1GB of RAM
Here is what I know,  I am sure there may be further questions so ask away!

I have tried upgrading graphics drivers as listed in this post.  https://askubuntu.com/questions/1065852/...ics-driver  That actually made the problem worse as I got some odd pixelation on screen.  When that happened, I removed the updated drivers.  Thanks in advance for your advice!

I will add that I have this problem as well. Works fine on my remote machines but on the host / main it chops up with out of sync audio. I thought I had isolated it down to a filesystem issue with mergerfs but the problem persists. It has gone away since I moved my "server" stuff to another machine and now pxe boot all of my kodi boxes. So remote works. Same host, chops up. This has been an issue for me for awhile, tried 28, 29, and 30 does it as well.

A core2duo is pretty low spec for mpeg2 decoding, especially with deinterlacing. Have your tried one of the less-intensive settings such as Bob rather than the default Deinterlace?

Agreed.
