I am fairly confident that this happens on program boundaries which quite
often happens to be on 30 or 60 minute boundaries.  I see this behavior
most often with 30 minute episodes of kid shows which have more chances to
fail in a given time period, and me and wife tend to not watch LiveTV.
 This originally tricked me into thinking it was a 30 minute buffer issue.
