Without knowing what release you're asking about, the question could be answered many ways. I answered 0 because I haven't had to RBR since 12A. Before 12A is was once a week (basically once during each early release when I hit the BSB on ESPN HD). None on 128 because I tuned to D* HD Local and none on 12A despite tuning to ESPN HD before going to Standby.
I was talking about in general since you have had the box. Is it constantly once a week? Several times a week every time you get the verticle stretch issue that was recently raised?
And... 12a has been out less than a week. I do not think we know yet how this version will shake out. Do we? So, sounds like "once a week" to me
Anyway thanks for voting!
