Using unbelievably old, unsupported and outdated software, I have found a way to extract the GPS data from the CF-100 video files. I don't think anybody has done this before (if they have, I haven't found anything yet). I can't guarantee this will work for you on your system, but, I will list all the steps I've done and post screenshots to assist. I'm using an AMD based Acer Aspire 5551 laptop running Windows 7 64-bit.
When done, you should have your GPS data available to you in a format of your choice, which you could then use to create a video of your speed and/or location using an animated map. You then simply load that into your video editor of choice to overlay on top of your actual footage. It is even possible to do custom designed speedometers if you want.
You can also tweak this method to extract the front video, rear video and audio streams from your raw footage however you fancy, in a similar manner to Gibson99's script.
P.S. I will make an example video up sometime, until then, some useful (and free!) post-extraction software I've come across:
Handbrake-
https://handbrake.fr/
Very useful open source video transcoder.
DashWare-
http://www.dashware.net/
After converting your files to MP4 using Handbrake, load them + GPX files into DashWare to sync and overlay all sorts of gauges. It's not a full featured video editor, however, there is a way to use Chroma Key to export only the gauges. You can also create a template of your favourite gauges and their on-screen size and positions so every new project matches up perfectly. Check the DashWare tutorials page.
GPX Animator-
http://zdila.github.io/gpx-animator/
Requires Java
Used to create an animated map from GPX files, exports to a video format you could then overlay in your main video editor. Takes a bit of tweaking to find the right settings... but it does work! This little gem may require a setup guide all on its own.
CycleCam-
https://sites.google.com/site/verymadmart/cyclecam
Requires Java and QuickTime, designed for Macs
Can create video overlay using GPS data to use with your main video editor. However, I can't get it to work on my Windows 7 machine.
GPX Editor-
https://sourceforge.net/projects/gpxeditor/
Useful for fixing and combining multiple GPX files (DashWare is best used with a single GPX file, as each gauge you use can only take data from one file).
