ESPN motion caches some stuff so the clip could still be on your hard drive. I checked my computer and had actual clips from as far back as 4/25 and damn ads going all the way back to 3/1.
If you still need the clip I can send it to you.
BTW, cached clips will be stored in a location similar to this:
C:\Documents and Settings\All Users\Application Data\DIGStream\ESPNMotion
