Hi really struggling with this one.

Have a brand new install first windows 7 now windows 10 on a client machine.

Installed mediaportal 2 and when i run it it attaches the server and shows the guide and recordings. Can play recordings but when i go to a live stream it comes up with the error.

Error invoking action 'StartTimeshift'

I have looked at the logs and i see the following.

I also had the "timeshift" error on a fresh install of MP2. In my case it was down to the MP2Server service not starting up properly. This was fixed by changing it to start "Automatic (delayed)".

See this thread. Might work for you.

Thanks for the reply. I did check that and restarted not only the service but also the server. I also changed the service to be a delayed tart. I really like MP2 but i have found the service to be less reliable that MP1 and have now reverted back which is a shame. MP1 strwams to the client without too many issues apart from Network spiking which i think is a local issue.
