How are you "converting" it? What tools/process?
Are you extracting the streams or re-encoding?

every time you re-encode anything you lose detail and quality. there is no getting past it. the only way to get the max out of any encode is to use the original source and do it once. so buy the dvd if you want to encode to mp4.

I've tried a few methods on different types of files with similar results each time i've tried:
demuxing the mkv and remuxing into mp4 container then converting (so the video stream would work in iTunes)
demuxing mkv, remuxing with just 1 video and 1 audio track in mkv, then converting to mp4
demuxing mkv, convert video to mp2, audio to aac and muxing to mp4 file
Might i just have to live with it?

Thats what i thought, and i think that's what i'm going to end up doing. I just wanted to make sure it wasn't something i was doing.

Why don't you demux AVC video and aac audio, then remux into mp4 container (i.e. direct stream copy)? That way you lose no quality
mp4 is a suitable container for AVC and aac
Unless iTunes (if that's what you want if for in the end) is doesn't support it.

Interlace is your problem here.
Your "after" shots show a clean drop-field deinterlace instead of IVTC or another better method.

That's what i'd LOVE to do. when i demux the file, the video is already (in this one case) aac, and the video is labeled as .h264
When i demux as mp4 the video comes out squished horizontally and the audio doesn't sync. It also has 25fps instead of 23.976, i don't know why. using mkvextract and yamb

It should work with avidemux
Open your video, select 'copy' for video and audio sidebar, select 'mp4' for container.
Then press save. (You have to enter full filename with extension e.g. 'filename.mp4')
Sometimes you have to open your video stream separately and then "point" to the demuxed audio by using audio=> main track => external source

Thanks i'll try that.
I also tried some other content demuxing from mkv and muxing as mp4 and works PERFECT except in iTunes, the video is real choppy and stuff. (even though the bitrate is only about 1000Kbps

ok so here's how the demuxing goes:
original mkv file:
1 video
2 audio
1 sub
and a few fonts
i take the video and 1 audio
now i have video.avi and audio.ogg i convert the audio to aac and when i demux the avi video i get video.cmp, what the heck is cmp?

can you open the original mkv with avidemux? (sometimes you can't if there's too much 'stuff' inside like subs, picture etc...)
run the demuxed "video.avi" with mediainfo => its already demuxed it should only be a video stream? why are you demuxing again?
i have no idea what video.cmp is
