My channels guide, all of a sudden went down to like 30 channels, from like 300. Troubleshooted all day today and yesterday. And I think the issue is that Socal Cox has pretty much put DRM on every non standard channel. Is that what my problem is?
Yes that explains why they stopped working. You could use your login with TVE.
I have to assume you use an HDHR Prime as your source.
If you look at the channel lineup on the HDHR tuner web page and see the DRM badge next to a channel, that's what the issue is.
