  In other words, it doesn't seem to be finding 
  the <title> or <episode> nodes, though it ought to be.

Note <xsl:if test="starts-with(//title, 'Q')
does not test if every title begins with Q, it just tests if the first
one does.

starts-with() expects two strings (just two) as its arguments, so if you
give it a node set for one of them, it takes the string value of the
first node in document order.

So //title finds all the titles, but to coerce to a string all but one
gets zapped.

I suppose I should grudgingly mention that this habit of silently
junking all but the first element of a node set to get a string value is
deprecated in Xpath2 and part of the "xpath 1 compatibility behaviour"
which is probably a good thing.
