You mean, are there still any dramas left on viki that don't have drm?
No. I think they've successively switched all their dramas over to DRM over the last few months. I just like to see the information in the list at one glance, I find it practical. There are still some small things without it, like trailers and stuff.
Chrome has also changed their key - the only one that had been made public was the Windows key - and it stopped working two weeks ago. So I currently have no way to decrypt the drm files anymore.
