Yes, this should be possible.
Play back the video via a <block>'s /bgstim. Set the <block>'s /timeout to the length of the video. Then, simply run a rating trial in an infinite loop. In a nutshell:
<block myblock>
/ bgstim = (myvideo)
/ timeout = 30000
/ trials = [1=ratingtrial]
</block>
<video myvideo>
/ items = ("example.mpg")
/ size = (50%, 50%)
</video>
<likert ratingtrial>
/ anchors = [1="slow"; 5="fast"]
/ position = (50%, 90%)
/ numpoints = 5
/ anchorwidth = 5%
/ branch = [likert.ratingtrial]
</likert>
