<div>What I have found is that several others

<p>I have found that using High Quality software
decoding to be more reliable and tolerates faults in
the broadcast stream. The cpu load is only moderate
- try it.<br>
</p>
<p>By the way this issue is still present in V31 so
upgrading will not help.</p>

<div>Thanks so much for the confirmation of the issue. I
have been wondering about using software but wasn't sure
my CPU could handle it. What specific settings do you
recommend?</div>

<p>I am on ver 31 using Opengl High Quality and cant remember the
exact settings for V28 but I think there was a High Quality
choice in Setup>Video>Playback>Current Video Playback
Profile</p>
<p>You should get ffmpeg decoding and if I remember correctly
vdpau double de-interlacer.</p>
<p>That config never failed for me on a combined Intel Haswell
front and backend with Nvidia graphics.</p>
<p>Note i still get judder with software decoding if there are
background tasks running so avoid that.</p>
