Apparently without any orbit-changing maneuvers performed (including the
initial two pre-programmed ones), it happened during the second orbit.

and http://www.spaceflight101.com/progress-m-27m-mission-updates.html 
both discuss the video as real.  The second link goes into more detail 
about when and how it was received.  On the SeeSat mailing list, Ted 
Molczan has calculated a preliminary decay time of between 7 and 9 AM 
UTC tomorrow (April 29), though it's not clear to me if that's based on 
the initial, apparently too low, perigee reported.  See the 
spaceflight101.com link for a discussion of the Progress M-27M orbit, 
which indicates a potential launcher issue.
