How does the 501 handle a sporting event that inevitably goes longer then scheduled? For instance, the NBA playoffs were always supposed to end at 8:30 PST, but never actually finished until around 9. The EPG would say 8:30. SO, would I miss the end of the game, or does the PVR know to keep recording just in case? Or do I have to tell it that I want it to keep going? Any answers?
