Website videos will not play since XP sp2

Archived from groups: microsoft.public.windowsxp.video (More info?)

Since I installed SP2 for WinXP home, I can no longer
view videos from CBS website. I haven't tried other
websites. I have RealPlayer and it's site is listed in
the allowable sections in security sections of Windows
and in Symantec Internet Security. I was able to play
videos from that website before.

The link to the video works, but when I click on the
video to play it, it looks like a flash of something
trying to start, but then nothing happens.

When I right-click on the link that says "click here to
watch", I get a popup box. I click on "Properties" and
get:

index.php?chap=1990&cat=27',758,517,'insWin','no');
