#110 Avidemux 2.8.0 cannot edit a TS Video File

[Andy Friends]

Avidemux cannot edit a TS Video File of 4.18 GiB.
When I open this file, Avidemux reports a video length greater than 8 hours.
It seems that somewhere in the video it encounters a problem and then it stops (Avidemux say 'cannot go to next / previous keyframe'). This problem is repeatable so I could produce a log or dump if I get instructions.
The problem is not evident with other editors but I prefer to use Avidemus.
So, as a workaround, I cut the part of the video with the problem by selecting the portion from the left to the message 'cannot go to next keyframe' and from the right to the message 'cannot go to previous keyframe'. I think the part of the video removed is one or two frames but, after this cut Avidemux indicates the duration of the video is 02: 04: 48.

Thanks for any support you can give me.
