[BUG] Audio loosing quality, even changing the bitrate to a bigger value

[Selur]

Afaik MeGui won't work since last I checked it also used MediaInfo and unlike Hybrid won't fall back to MPlayer in case MediaInfo fails.

What you want to try is a tool which:
a. is based on ffmpeg/libav
b. is freshly build since even ffmpeg/libav didn't report such files properly a few month ago either.

Alternatively, what I probably would do if I needed this to be over with asap:
Convert the audio using ffmpeg into a format which is better supported, in example flac (which is lossless):

"F:\PROGRA~1\Hybrid\64bit\ffmpeg.exe" -y -threads 4 -i "F:\# Backup\#Pasta Downloads (iniciou 15.12.17)\Sonic Unleashed XBOX 360\PS2_MOV\SEGALOGO.mpg" -c:v copy -c:a flac "F:\# Backup\#Pasta Downloads (iniciou 15.12.17)\SEGALOGO_WITHFLACAUDIO.mkv"

and convert that output file with Hybrid.
