Many thanks again.
Now having wiped my setup whilst resolving the above, I'm trying to get TvHeadend set up again and am struggling with channel icons. Last time (2 weeks ago) when I first set it up, I couldn't get my head around the picons/channel icons and ended up manally editting every channel to point to a url for it's logo - very time consuming. As I'm starting again I'd like to do it smarter and work out how to add them en-masse - but can't get it to work.
Here's what I've done so far:
1. Download picons and saved them to my network drive, folder: Public/KodiPicons
2. Mounted this network folder to the openelec box using the successful mount command we worked out above, namely: mount -t nfs IPADDRESS:/nfs/Public/KodiPicons /storage/picons -o nolock;
3. In TvHeadend webpage setup, used the following option: Configuration > General > Picon > Picon path and entered "file:///storage/picons"
But the channel logos are not loaded. Any idea what I'm doing wrong now?
