To me a network problem sounds not so realistic. Why should a network problem happen only, if two clients want to access the same channel? If a port is locked or similar, the issue would be always. Also the logs do not indicate something in this direction.Ok now i buyed for testing the DVB Viewer Pro Version and Media Server Plugin.
And installed on 2 Clients Kodi with thje DVBViewer Client Addon.
Same Problem like with MP2.
Client 1 starts the first HD Channel, all is fine
Client 2 starts the second HD Channel, Client 1 begins to jerk and freeze
Client 1 switch the another HD Channel, all is fine
Client 2 begins to jerk and freeze
Therefore it is no specific MediaPortal 2 issue.
Maybe a Hardware Problem or a network problem.
If it is a network problem, i don't know where i should begin to search, cause i have no special experience in this.
If it is a hardware problem, then i think i must change the TV Tuner/CI-Modul/CAM and that could be very expensive.
I still have a Cine S2 V6.5 laying around here. So if nothing else helps, you can send me your CI/CAM/Card and I can test it here with many different TV Solutions. You will get your stuff back asap after the test, for sure
