Understanding why a recording is pixelated or has strange artifacts is an ongoing issue that has caused a lot of frustration for users over the years. Figuring out why this is happening has always been difficult and has involved guessing and fiddling.
We've been logging
[SNR] log messages for every HDHomerun-based recording for a while as we experimented with different ways to quantify if a recording had issues or not and how bad it was. We recently had a breakthrough that has allowed us to represent the numbers in a more meaningful way and has given us the confidence to display them in the UI.
In the latest DVR pre-release (press-and-hold on Check for Updates to upgrade to it) you will be able to see this additional information to help identify the source of recording issues.
v2020.02.28.0428 we will print additional fields in the
[SNR] log message:
sigerr=10%indicates that 10% of the recording was impacted by signal issues (generally due to OTA antenna reception issues or cabling issues for Cable TV)
neterr=15%indicates that 15% of the recording as impacted by network issues (generally due to connection between the HDHomerun and DVR having issues, often times because of the use of WiFi or Powerline)
err=17%indicates that a total of 17% of the recording was impacted by the above two kinds of issues (it is possible to have reception and network issues happening at the same time or different times)
Here is an example log message with OTA reception issues for 5% of the recording:

To make it easier to find these issues without having to dig through the DVR logs, we are also showing a warning when selecting View Details for a recording:
