yes im not sure why but its the box resetting (used to see it myself and certain circumstances made the box crash and reset).
Needs the reset to usb wire connecting and possibly the modified code incorporating reset patch programming to sort - altho that doesnt stop the box crashing but that can be worked around im sure (from memory is the wdt active which resets the box after x secs if tv2 crashes or hangs, this is prevented with the wdt patch in the nk.bin i think)
