I hope this helps, I found this info on "screenhead.com" web site. The A&E site was almost useless. I hate sites that give such little information, anyway here is what I found:
It’s a bad day to be human this Memorial Day when THE ANDROMEDA STRAIN infects the airwaves. The four-hour original A&E television event will premiere in High Definition on Monday, May 26 from 9-11 PM ET/PT and Tuesday, May 27 from 9-11 PM ET/PT.
Note to webmasters, please give the year also!!!
