nitoTV Playback Stopping When Changing Connection State With iTunes

While nitoTV is playing VIDEO_TS from USB-attached external hard drive, it exits playback and kicks back to the nitoTV menu when either of the following occurs:

 1) iTunes loses connection with the Apple TV (if it was already connected before playback begins), or

 2) iTunes connects to the Apple TV (while VIDEO_TS is playing)

Ideas? ... short of the obvious solution: making sure iTunes is not connected before staring nitoTV / VIDEO_TS playback.
