DVB-T2 transport stream handling of errors on export

[hamoph]

Using the August 2.8.2 nightly build (and 2.8.1) on a Mac.

The linked DVB-T2 transport stream has an issue at 5 seconds - if the ts file is played in VLC a short moment of pixelation is seen. When played back in avidemux this is handled seamlessly without the defect. However on export from avidemux without re-encoding - e.g. as .mp4 copying the audio and video, there is frozen frame that lasts several key frames.

Is there anything more that can be done to make the exported file more like the way playback is handled in avidemux? Thanks!

In case it helps - most of the I-frames are I-FRM, but where the issue occurs they switch to I-TFF for 4 frames, and then playback resumes with the next I-FRM. Thanks
