Sorry about this, I just realized that I had only fixed the "specials" videos (newest, most played etc.) and not the generic ones. Please try the attached DLL!
@teevee:
You just need to paste the .dll to the right folder. On my win 7 setup its here: Programmer/Team Mediaportal/Mediaportal/plugins/Windows/Onlinevideos
You can publish the sites right away, no need to wait for a new OV version!
From within OV Config, you are already the Owner and maybe simply forgot that ?
