When there is inclement weather or errors, especially off 129W as the satellite wobbles around, instead of just freezing the picture in the output circuit as the old 6000s did that could be corrected with a quick channel change and back, you have to reboot the ViP211 and go through the incredibily long startup sequence.
It's a real PITA - especially as the video signal is continuing to come in fine - its just the output circuit that is hosed to your set that is hosed.
