Video streaming puzzle

I recently re-built my HP Pavillion DV6775 with Vista Home Premium SP2. I created three user spaces, two of which have admin priviledges. There is an internet page that I used to visit where they have a live video feed. After the re-building, I can only watch the feed from the non-administrator account. Does anybody know whow to solve this? I checked the IE7 set ups and they're identical. Eventhough this is not a big issue, it puzzles me (and bugs me!)
