Unfortunately this cannot be changed because we need to know the origin page where the user is visiting from so that the back to listing would link the user back to the correct page.

I will create a ticket internally so that there will be a canonical tag added on the video item page in 2.0.7. This way, Google will not consider this as duplicate.

By the way, you can actually just add the "from=" in your Google webmaster account so that it knows these are variables they should ignore.
