What did you mean by "add"? I can't find a mutex in cControl.

Did you mean this?: (myMutex is a private cMutex from cMyPlayer)

bool cMyPlayer::start(const char *path)
    cMutexLock MutexLock(&myMutex);   
    cRecording *recording = Recordings.GetByName(path);
    if (recording) {
        cReplayControl::SetRecording(NULL, NULL);
        cResumeFile resume(recording->FileName());
        cControl::Launch(new cReplayControl);
       // cControl::Attach(); //will done in the foreground thread
        return true;
        return false;

In this case I only protect my own function. This will protect that my 
thread can't recall start until it is done. Thats OK.
Or did you mean that I need to patch the cControl by adding a Mutex and 
protect all memberfunctions? If I do so, will you add this patch to 
upcoming vdr versions? I don't want to patch all upcoming versions.
