3 crashes last night on my main windows HTPC. Have disabled the webserver I've got Argus working pretty well, recording and live-pause both work really well. The biggest drawback is lack lack of mobile apps I'd say. Any kind of 'remote record' type functionality needs to go through the Argus backend not Kodi, there is a fairly decent web portal for it but to gain outside access the machine will need to be on all the time and you'll need ports forwarded etc.
Having said that, I have 3 devices (2 windows, 1 android) that are all synced by the same central sever so recordings are available on all 3 including resume points so it works pretty well, but not quite as good as Sky+. Wife friendly I'd say though...
