The video you have requested is either unavailable or is being blocked by an ad blocker installed on your computer

I just started having this exact same problem.  Last night I was watching cbs videos fine, today I am getting this error message.  I suspect it is a virus or malware of some kind.  I am running a gateway laptop with windows vista.  Since it was working fine up until right now and I didn't do anything but play starcraft I think it was something that infected my computer earlier and now started doing this.  I have norton internet security 2010 running.  I also ran spybot s&D and malware bytes.  I was using chrome but to test no add-ons I used internet explorer.  Without add-ons the video will not play.  With every add-on disabled except the adobe flash plug-in, I still get the error message.  I wanted to make sure that just using a different browser wouldn't fix it.  Nothing changed from one day to the next and it was working perfectly.  Now this irritating message.  It might be worth noting that with repeated reloads of the page I can get the video to play again, but it usually gives me the error again at a commercial.  I think there is some software spamming something out of my computer and I need to know how to make it stop.  Let me know if you need any more information.  hulu videos work fine, no other web pages or internet functions seem impaired.

I'm having the same issue... while trying to watch CBS.com (upcoming survivor contestant videos)... Not sure if they are really unavailable or if it's

my pc.  I don't have a pop-up blocker enabled/installed.  It must be Cbs.com as other websites are working for me.   @MCprole - You are probably

experiencing the same issue as I am. I highly doubt its malware/virus because I am 100% sure my PC is clean! =)

I'm having the same problem everything was working last night, I was watching some Star Trek classic episodes and today when I try to watch them again I get that messege, since the problem is within the time frame I started to have the problem and NBC works fine my guess is something to do with CBS. I even dare say it has to do with their sponsors streaming server. that just my two cents.

I was having this problem too.  I use Windows 7 Ultimate and IE8.  The key to this problem was that I also use the Google Toolbar.  I turned the toolbar off and the problem went away.  If you are using any toolbar that includes a pop-up blocker or other security feature, try turning it off.  I have also found that turning the toolbar back on does not bring the problem back.  Hope this helps.

I used google chrome ... works fine but didn't work with firefox or Internet explorer.

I have a macbook pro and I'm having the same problem while using safari.  It's BS.

Same issue.  IE, Firefox and Chrome experience issue.  CBS has a poor system.

This morning while watching a CBS program being streamed from Hulu through Playon (WMPlayer on Windows7 through my home network) onto my Samsung LM40C630 I received this message in red font at the top of the screen after about 20 minutes into a show.  The only change I made recently was to add AvaStream to my PlayOn.

I am wondering if the warning message is due to the DNLA related browser running on my TV?  I am not up to speed on that technology and my Samsung's DMP (digital media player) interface has very poor control.  I'm going to try viewing CBS on my PC next using WMP and see if the warning message appears.

We had the same problem on a Mac with Safari watching Medium on CBS.com. Interestingly we switched to Firefox and had the same problem with one small wrinkle. The Ads didn't play but the show continued playing with the message and the black translucent overlay on top. It made the show dark but still watchable. The other downside was that no controls were available to control the show. 

This seems to be a problem with cbs.com and their ad platform. I am pretty sure it is not a PC/Mac or browser issue.
