I'm seeing motion artifacts/lines on my tv when viewing mostly hdtv. It happens in MC22 and 23. Any lateral panning of the camera or sudden movement on screen causes smearing and short black lines to appear. Some programs are worse than others, sports are particularly bad due to the frequent movement.
I suspected my tv as going bad but if I use VLC instead of MC to play the stream, the artifacts are gone. I've tried playing with the video settings including ROS and ROHQ, and custom with most settings turned off.

Any suggestions?

This is a NUC6i3 to a Sony KDL32705B tv, signal supplied by an HDHomerun Prime (DVB-T2)

I was going to suggest it might be the Motion settings in your TV, but if the same recordings play well in VLC...

Hardware acceleration for video on/off?
Does it happen on Live TV and on recordings?

Post up your JRiver Benchmark results.

I'm going to do some more experimenting tonight but in the meantime here are my Benchmark results

That's a fair score, but not a good one.

With Red October Standard, I think you say it still is a problem.  Is that correct?

Yes, until recently RO Standard has been fine but ROHQ has all sorts of issues of screen stutter and breakup. Until the last few days, things have been fine so I dont know whats happened. But I do have a recording which shows chronic artifacts which I see when I play back on a different monitor. Not quite sure what to make of that.

So, as I'm considering another NUC for the lounge, do you recommend a bit more power? I thought the i3 would be sufficient but how far would I need to go to achieve ROHQ? Can any NUC manage that? Or is it a graphics chip issue?

Just to complete this thread for anyone reading, as stated elsewhere a reinstall and complete re scan of all tv channels has cured this issue.

It was a strange one, but the status quo has been restored.
