OK, I think I've discovered something here...
I just did another short run and when I started the car I waited until the bottom LED (GPS) went on solid. I then drove to the ATM to pick up some cash and on the way back I set the cruise control at 50mph. When I got home I uploaded the data to my PC. I looked in the data for the place I knew I was going 50mph and the speed value was about 43,5 and I then multiplied by 1.1508 to convert from knots to mph and the result is 50.1mph -- just as it should be. However, when viewing this same area in RV it shows the speed in the video speed stamp as 80mph while the speed indication at the bottom graph and speedometer within RV as 27mph. So, the value in the video speed stamp, though it says mph is actually kpm (50 x 1.61 = 80). The display of 27mph in the speedometer and graph with RV appears to be equal to 43.5/1.61 or actual speed in knots divided by the kph/mph conversion.
When I view this trip with the QtPlayer the video speed stamp not surprisingly says 80mph but the speed indication in the lower right speedometer indicates 46mph or 83kph.
One more thing that is an issue...
As I said, I waited until the bottom LED was on solid before driving and when I played back the trip the lat/lon values for the first couple miles were way off -- off by a couple miles. Then, about 2 miles into the trip the lat/lon coordinates became accurate. This error was obvious in the on screen map from within RV and QtPlayer and I doubled checked by entering some of the erroneous coordinates into Google maps and that confirmed the error. I seem to recall a Youtube video (Techmoan) that showed gps errors with the 0803.
So, in summary,
1. The 0806 does appear to be recording the speed and elevation into the gps log but RV does not display it. (0806 recording data correctly)
2. The speed value in the log is correct but in knots.
3. The video speed stamp is displaying the correct speed but in kpm even though the 0806 is setup to display mph and the video speed stamp indicates mph. (problem with 0806)
4. The speed displayed in the graph and speedometer within RV is configured as mph but is actually showing the speed as knots divided by 1.61. (problem with RV)
5. The speed displayed in the speedometer within QtPlayer appears to be in error (high) by a small amount . (problem with QtPlayer)
6. RV is not displaying elevation data even though the log file contains elevation data. (Problem with RV)

Thanks for giving good detail
As I said, it is mostly working for me but I'm using different options and a different RV.
Comments on your points - mainly because I don't want Rayman changing the log from knots to kph or something similar!:
1. The 0806 does appear to be recording the speed and elevation into the gps log but RV does not display it. (0806 recording data correctly)
I have never seen RV display the altitude, I don't know if the altitude is in the video stream, maybe it's just in the log files which RV is not using?
2. The speed value in the log is correct but in knots.
GPS speed is normally stored in knots so this is correct, you convert it to what you want when you display it.
3. The video speed stamp is displaying the correct speed but in kpm even though the 0806 is setup to display mph and the video speed stamp indicates mph. (problem with 0806)
I haven't tested this on mine but I think the problem has been reported in a previous version.
4. The speed displayed in the graph and speedometer within RV is configured as mph but is actually showing the speed as knots divided by 1.61. (problem with RV)
Mine is working, maybe you could try a different version of RV. I think here are a few reports of this problem in the 0805 section and there is a beta version of RV with a fix.
5. The speed displayed in the speedometer within QtPlayer appears to be in error (high) by a small amount . (problem with QtPlayer)
I always avoid QT after issues years ago so can't comment.
6. RV is not displaying elevation data even though the log file contains elevation data. (Problem with RV)
Covered this in 1. - I'm not sure the elevation data is in the video stream but if it is then maybe Rayman needs to send the format to the RV team for a future fix...
