Format settings, CABAC : Yes
Format settings, ReFrames : 2 frames

Audio

Format : AAC
Format/Info : Advanced Audio Codec
Format profile : LC
Codec ID : A_AAC
Duration : 1h 30mn
Channel(s) : 2 channels
Channel positions : Front: L R
Sampling rate : 44.1 KHz
Compression mode : Lossy

i wan to keep the video quality and audio quality as it is, i only want to change the container to avi. So i open up Xvid4PSP 5 and choose the following settings:

Format: AVI HArdware HD
Denoise: Disabled
Brightness: Disabled
Video encoding: Copy
Audio encoding: Copy

but everytime i get an error saying: "The function DeleteComments was called on a stream[?] that hasen't been initialized with SetSource"

what to do? I guess this is due to the option AUdio encoding: copy. I've even tried to encode the audio to another format, but then there is no sound in the video only an awfull error-like sound!

You could try avidemux, under video and audio choose copy, format: avi and save as avi.

But why? For computer playback leave it as mkv. And most other devices does not support avi with avc video. Maybe convert to mp4 instead then, https://www.videohelp.com/tools/sections/all-in-one-mkv-to-mp4-avchd-ts
