So how about the birth marks on the side of her right upper arm (a bit up from the elbow)?
They are visible in the video at about 2:23
And they can also be seen in this photo from Met-Art.

btw, I LOVE LIZA, that link you posted to a porn star named Dasha does not appear to be the same as the girl as in this video.
All of the above said, I am still not 100% convinced that it is her either. What makes this really difficult is the previously mentioned poor film quality of the video and the fact that Met-art and Voronin photoshop their pics (way too much IMO).
