Stupid new YouTube. How do I remove watched videos in my subs?

I think its a cookie thing cause 99% of the time when I watch a vid.. it goes away (afew exceptions). Then if I run one of my apps like Spyware terminator, Spybot S&D, or some other thing I do that deals w/ HD cleanup (since I usually run them all back-to-back havent isolated which one is the culprit)... many of them pop back up as unwatched.
Yes it can be annoying since many (like those here on Rev3) have preroll ads you need to sit thru before you can move on and it is considered "watched"
