I go through the install OK though there are a few channels which don't appear (Together TV+).
I decide to uninstall all and do it again by not using the supplied mux lists as they are massively out of date (at least Beacon Hill is).
However while experimenting I recorded one program that I want to keep, so I select it in Finished Recordings and click Download, and I get an immediate request for credentials, pre filled in with hts as user and password. I try this with no luck. At the same time the recording gets moved to the Failed Recordings folder.
I've seen lots of "403 Forbidden" errors before but never one in this particular situation
