Hmmm, I dont have any any of these problems with the videos, particularly the SSP, but then again I dont play videos within IE. All the videos play entirely without stopping, which to me says they are not corrupted. I use Open and then WMP plays it or I will Save As and watch them that way.
"I expect to pass through this world but once; any good thing therefore that I can do, or any kindness that I can show to any fellow-creature, let me do it now; let me not defer or neglect it, for I shall not pass this way again." - Stephen Grellet
