Like you, I am unable to view the videos. It looks like those are just leftover "live" links from the original broadcast. I, too, would like to be able to watch those past games, but it doesn't appear goduke has added them to their archive yet (if they ever will).
In earlier threads I posted about not being able to view the "test video" when trying to sign up for Inside Access. In case anyone is still wondering, I just wanted to let everyone know that the live broadcast of the Shaw game worked perfectly well for me despite not being able to view the test video. Thanks to the couple of you who did respond and encouraged me to sign up anyway.
All in all, I think goduke.com needs some attention. Maybe they are understaffed, or maybe there are just a few students keeping it together, but in addition to the test video not working there are a number of other issues with the site. I guess I won't get into all the details, but there's a lot of stuff that needs updating and a lot of links that don't work. I had to create a new account to sign up this year due to missing (eg "renew") and misdirected links, and it's quite confusing when you enter your credit card info, hit the submit button, ...pause... and are then redirected back to the original sign up page with no order confirmation. ... So I just made a new account, hopefully I don't get charged twice like last year. Also, the troubleshooting tips are completely outdated, and the customer service links either don't work, or if you find one that does it kinda doesn't matter anyway since you're not going to get a response. It worked for me in the end so I'm happy, but they must lose some visitors.
