The links:
https://bitstreamtools.com/download/downloadsetup0760.php
https://bitstreamtools.com/download/downloadsetup0815.php
are broken. The northernhd.com download site doesn't exist.

This is not an analyzer. It's a packet browser. I use it.

I remuxed Ticket_11055.m2ts with it. The tsRuxeR version is much worse.
I couldn't find an analyzer.

Not that I could find.

I removed the audio stream (PID: 4352, i.e. 0x1100). I didn't expect that to make any difference,
