Interesting, what's a webstream URL that fails?
Bob thanks for chiming in, I hadn't actually tested the webstream in a few months and I got a very pleasant surprise.
The HDhomerun network tuners expose all their channels as webstreams, but they're local in-LAN streams (so I can't just link you to one of mine). They look like this:
http://192.168.1.10:5004/auto/v5
Where 192.168.1.10 is the local ip address of the tuner and where 5 is the channel number.
Interestingly, those webstreams now play in MC (they didn't earlier in the MC25 release cycle)! That means I can setup bookmarks for MC and can have some (rudimentary) live TV functionality right now.
That said, given that the TV playback for HDHomerun tuners at least appears to actually work in MC for linux right now, is there any chance we could get an option to turn the TV menu options on so we could download guide data? That would be a dream (it's one of the last linux transition sticking points for my wife).
Regardless, I'm excited I can watch live TV in MC for linux!
