Ravi, Thanks for your replay. Related to external access subject: if I need to create dynamically (during execution) a node (such as a parser node) I need to have access to iPlayerNodeRegistry->CreateNode(..). I noticed that the access to the iPlayerNodeRegistry is given only to DownloadManagerNode via iSourceNodeRegInitIF->SetPlayerNodeRegistry (..). How could I have access to the iPlayerNodeRegistry from a node that is not a DownloadManagerNode? One cumbersome way to solve this issue would be to create my own registry and all the necessary functions to populate it with nodes and recognizers, in other words to duplicate the implementation from the player engine.
