Hi Guys, I need some help to understand the TVClient

1) when the tv-server crashes I get an SQL Server Client Error on MP, is there a description how client and server communicate.. e.g. time frame.. time outs etc???

2) sometimes I have to reboot or at least restart MP to get the updated channel list..

Is there any kind of documentation to understand this communication and heartbeat stuff?????

as I am not a programmer I cannot read the c# code

Regards Robertino
