Comment (by ramitbhalla):

 BTW if I use this command, then ffmpeg detects the duration correctly
 after transcoding:
 {{{
 ffmpeg -probesize 100M -analyzeduration 300M -y -i "..\Wrong Audio Track
 Selected - Hearing impaired.wtv" -vcodec mpeg2video -qscale 0 -map 0:3
 -qscale 0 -an -f mpegts test.ts
 }}}

 This also works fine
 {{{
 ffmpeg -probesize 100M -analyzeduration 300M -y -i "..\Wrong Audio Track
 Selected - Hearing impaired.wtv" -vcodec mpeg2video -qscale 0 -map 0:3
 -qscale 0 -acodec copy -f mpegts test.ts
 }}}

 The issue is with the -acodec copy -map 0:a parameter. without the -map
 0:a it works fine.

 When I use this command also it works fine:
 {{{
 ffmpeg -probesize 100M -analyzeduration 300M -y -i "..\Wrong Audio Track
 Selected - Hearing impaired.wtv" -vn -acodec copy -map 0:a -f mpegts
 test.ts
 }}}

 Just when I use video and audio together with the -map 0:a it creates an
 issue.

 Hope this helps narrow it down.
