I have a VIP722. The timer for HBO Premier Episode: The Newsroom on ch 465 SPORT is in my recording schedule as well. Fortunately, it is skipped due to priority. I have new episode timers set for Letterman & Kimmel.
The strange thing about the rogue HBO timer on my dvr is that it scheduled for 11:32pm - 12:47am (PDT). When I look up ch 465 on the programming grid, HBO Premier Episode: The Newsroom is scheduled for 11:30pm - 12:30am (PDT).
This isn't even a new episode of The Newsroom. This is the series premiere, which originally aired in June 2012. The new season is still more than 2 months away.
