just tell us which video/videos you are interested in. there are enough ppl here with vpn or with true US residency who can check if your show is posted in HD on cbs.com
if your video/videos is a popular TV series episode (or complete season or complete series), then it's maybe easier and more rewarding to download them from
Amazon Instant Video for FREE.
you should appreciate my investigative screenshots which are clear enough for both the clever and the dumb to understand in a direct or indirect way:
the existence of the tiny "HD"-button does not depend on you or your system. it depends on the very video itself. if a particular video exists in HD-format, then there
will be the tiny "HD"-button (e.g. the one Survivor episode) for everybody in the world equally the same.
here another original fresh screenshot. look for which video clip there is some HD-button and where there is only the "HQ"-button. not every show in the HD-gallery has the HD-button.
Unless you (or somebody else from The States) proves me wrong (e.g. by screenshots of emails by CBS responsibles, or other kind of authentic, official and original screenshots) with what i've stated in this thread, this was now the final word on the existence of CBS HD videos.
