Yes the Twonky media server works, yes remote access works. What may not work with some of those changes is the searching feature when connected remotely and with icons being created for viewing when connecting remotely.
The other thing that may not work properly is the Capacity section of the My Cloud Dashboard. Since I started using a startup script to improve sleep time the Video, Photos, Music Tracks for the Capacity section indicate zero rather than showing a capacity. Doesn’t bother me since I rarely access the Dashboard these days.
No idea. I generally have that line commented out, but left it uncommented so one can experiment. There was past discussion in other threads about disabling cron.
