Tonight had a thunderstorm producing low signal levels on ku. Using VIX 153 in flash, tuned to a normally weak transponder and it went into a search loop rendering the rc keys useless. Only option was to turn power off and reboot. Tried again to tune in the same transponder and it produced the same result. After a reboot to VIX, selected ATV from the open multiboot menu and rebooted to ATV. Went to the same weak transponder and ATV went into the same search loop but allowed an exit by pressing the exit button.
