I had looked at that website before , but before the added section at the bottom of the page. I followed the instruction 5times over and they didnt help either.. I checked all again codecs and and after disecting file by file for hidden codecs my Cdrive, I found a hidden, unnamed version of Xvid that was a built in component of Auto Gordian Knot. I uninstalled Auto GK, then reinstalled it with out the Xvid component (just to check) and the media files have been smooth sailing … so far. If a the COM Surrogate arrises again, I'll post again.Thanks for your help, Mitz.
