I really don't know what the problem is. It's ok for some to report an issue with cwtv, and we are then all happy when 6.2.3.1 came and looked like it fixed it.
Now someone else comes along and shows that neither 6.2.3.1, 6.2.3.2 works with cwtv.
I personally don't care for, nor what, yt-dlp reports. Two other downloaders download not only movies, but series from cwtv fine, yet streamfab can't.
If not for the SF log, I would not even have known that it's trying to save as s01E101, as I never got a file to view.
For all we know, the other programs use other means to get the proper info.
I more than likely would have been ok with SF saving as S01E101, as I could then rename it to what I want, but SF can't even do that, I never even got a file.
I don't get why the continuous disagreements between users or members when this all should be focused on Streamfab, and its lack of working properly, and for the extreme price everyone pays for a program that doesn't work right, in many ways, but also I give credit for when it does work right.
It's more than obvious that not many here who use streamfab want to bother or be bothered with a command line program, like yt-dlp, that only supports none DRM, as many things on many sites are DRM. I am one of the first to tell others when standard YouTube videos stop working in SF to go to a free YT downloader, as they almost always work. And many have GUIs built around yt-dlp. Heck, even JDownloader will work for YT standard videos, again, not easy to find ones that support the DRM YT videos.
As to how two other programs do it, I can't say, people would need to ask them. They both were also able to get Amazon series listings the whole time SF could not, and neither needed a patch nor update to fix that.
One main advantage to streamfab is you know, when it works, you're getting as pure a download as possible with hopefully the best video/audio available.
So let's keep to reporting issues and getting streamfab fixed and become the best downloader ever possible.
