Same here since 042921 on android and windows. I have HDhomerun + DVR going, although it appears to happen with the DVR service on or off.
It's super annoying because it does this stutter thing every 10-30 seconds, and it makes watching live TV super painful
. It doesn't appear limited to any particular station. My observation: the stutter seems to be the result of the tuner syncing the video to the audio on some sort of increment.
Let me know if this doesn't work, but you can see it stutter notably around 3s, and a few more times thereafter. As mentioned, it does this continuously every 10-30s, more or less:

My tuner signals stats are all 90-100% and I saw this same issue prop up about a year ago only to have it disappear around June 2020. It was gone until just recently - around patch 042921.
