Another rescan attempt today produced this error "drm not supported". So that's at least 3 different errors I've seen. I tried to load it up in a web browser but it wanted to install flash so I gave up.
For the folks that have this channel working 100% (including the Channels DVR developers), can you please list some additional information about your setup? Things like geographic location, host operating system, chrome version (this seems to be required on Windows?), TV provider used for authentication, etc.
