[Novalug] Video Editing/Movie Help!!

I'm trying to integrate as much Linux at work as I can, but now I need help with video (the watching kind, not the graphics card kind).
 
Long story short, as part of a project of sharing knowledge I've recorded a screencast using Kazam in Ubuntu and rendered the video project in Kdenlive.  The video plays on both my Linux boxes, on my Win 7 box, but not on my Mac and not on another XP machine.  I need this video to be in a standard format with the right codecs to play on any computer.

The original .mkv file plays great on both Linux machines.  I recorded audio both into the .mkv file (external mic to 3.5mm jack) and using a miniCam setup in the room where the presentation was done.  The audio on the miniCam was much better.
 
In Kdenlive, I used the screencast video (.mkv) and the miniCam audio to complete the final edit of the video.

Here are the details.

Kdenlive Project Settings:
HDV 1440x1080i 25fps

.mkv video clip info:
00:37:41:17  244.3 MiB
H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
1280x800 frame size
30 frame rate
1.0 pixel aspect ratio

miniCam audio clip info:
PCM signed 16-bit little-endian
2 channels
32 kHz

Kdenlive render settings:

f=mp4 hq=1 acodec=libmp3lame ab=384k ar=48000 pix_fmt=yuv420p vcodec=libx264 minrate=0 b=10000k b_strategy=1 subcmp=2 cmp=2 coder=1 flags=+loop flags2=dct8x8 qmax=51 subq=7 qmin=10 qcomp=0.6 qdiff=4 trellis=1 aspect=%dar pass=2

rendered file propterties:
.mp4 (MPEG-4 video (video/mp4))
37 minutes 7 seconds  981.9 MB
Video Dimensions: 1440x1080
Video Codec: H.264 / AVC
Video Framerate: 25 fps
Audio Codec: MPEG 1 Audio, Layer 3 (MP3)
Audio Channels: Stereo
Sample rate: 48 kHz
Bitrate: 320 kbps

This video is going to be viewed on computer screens so it's probably way oversampled, but I'll worry about that work flow later (I'm just getting into video editing.).  Right now I just need this file to play on any computer.

Any help out there?  Please, please, please?  I'm hoping somebody will say something like, "Oh, no problem.  Just run it through ffmpeg with these commands and your set."  If not, I'm willing to undertake more laborious steps.

Later,

Mark
