When you link to a Youtube video from MRH, the forum software automatically tried to embed the video so it can be watched directly in the post.  This is great except it does it wrong and many users browsing the forums with tools other than a Desktop PC or Laptop cannot see the video, they just see part of the link.

The bad video post looks like this:

Here are the steps you can take to fix your video when you see that it is wrong:

This works using the firefox browser, other browsers may not work this way.
If you cannot copy the embed code from the video itself, follow the instructions for getting the code from the youtube website posted here.
 

Step 1: Right click the video and choose "Copy embed code"

Step 2: Edit your post

Step 3: Highlight and delete the Youtube Link

Step 4: Click the Embed Media button - it looks like a Filmstrip.

Step 5: Press ctrl+v to paste the code into the text area

Step 6: Click OK and Your video should appear in your post 

Step 7: Save your post

Your video should now be in your post in a format that everyone can see.
