Ok I swear this is the last ... It was partially a settings problem and partially a code assumption...

The NuppelVideoRecorder.cpp looks to the System default instead of the specifics for the channel for recording and in RecorderBase.cpp it checkes for ntsc, ntsc-jp and pal-m and sets the video_frame_rate = 29.97 .. which is great if the default TVFormat is one of those, otherwise it assumes the format to be pal and sets the video_frame_rate = 25.0. So hopefully this comes in handy for someone else. If you have more than one TVFormat you are recording in only the default will be used. I doubt anyone else has run into this.
