Serviio

I have Serviio installed on my mac and use it to watch only streams through my home LAN on various devices.

It works perfectly except for the following:-

1. On all devices I cannot see all online channels, I have 50 or so sources programmed on the server but only 30 appear on any device. I have tried restarting the server and no difference. Is this a limitation of the server?

2. I have no sound from the online streams on Playstation 3 but Playstation 4 is fine. Why is this?

Please help

No enough info to help. The URL's have probably expired.
Do all "live stream" types get the green tick when you "Check URL stream now"
If so give examples of URL's that worked and ones that did not including Source Type.
Are the 20 missing ones in sequence at the end or random thru your 50?
Are the 20 missing ones all the same type?
Post the debug log for a clean startup where you display your list and play a displayed stream.
