But this would also mean that there would have to be a lower limit to the watchdog timer that is larger than this limit. The original problem is apparently some deadlock in the area of cSkins::ProcessQueuedMessages(). As you already found out it only happens if the message timeout exceeds the watchdog timeout. However, I would actually expect that to work, because AFAICS there is no place where VDR actively waits for the message timeout, so the main program loop should be still running if a message is displayed. I'm afraid I don't have the time to dig into this now. If the message timeout is small compared to the watchdog timeout, all is fine. If somebody can point out where the deadlock happens, I would appreciate that.
