Yes, host it for us because i work with video editing all the time.
This is important too-
Some media devices have 2 ways to exporting video off of itself and if you do it the wrong way, it will come out corrupted.
I do not know the terminology so try and do this yourself first-
First off, does your camera allow playback of the videos it records on the device itself?
If it does, try that first! IF it works, then we know the files in some form work fine.
If not, as suggested earlier, try and play them in the software it came with on a computer.
If it works, then go into Computer and look and see if your camera has it's own partition or if it's listed as some sort of portable device only or media streaming device.
However it is, the default method it uses to connect to computer is how you need to move your files off of it to your computer.
