Not from that page, no. But I have been able to get them to work(though, not in the browser), it was a different page and I right clicked on the video box and hit the play in real player option.
Wow. That is bizarre. I upgraded to RP 10.5 awhile ago and the videos work fine. Maybe there are some clips on Meguiar's website that would work. I think they use Windows Media Player for their videos.
