Firefox Adblock Plus can block in-video ads on own3d.tv streams and vods. Chrome Adblock Plus cannot do the same.
It would be great if you found a way to block the annoying ads which are played back before every new stream.
Own3d.tv
Re: Own3d.tv
Most likely not going to happen in the near future as Google has to fix that in Chrome itself: en/known-issues-chrome#itemtypes (last item).
