The people at DVBViewer are quite firm at the stance that it has to be a driver problem. As it presents to me the Recording Service expects something from the driver when a session/thread/instance is closed that does not happen, so it remains in a state that marks the driver of the CAM as "inUse" or in some other way inaccessible.
Since other tools like MediaPortal TVService seems to mangage the task, maybe there is a method to reliably close/kill the thread that the DVBViewer people don't know about.
Please help.
