I didn't feel like digging into grabbers so I used the alternate code
path approach in the attached patch. My first attempt used one code
path for the main query. The OR for category or genre match made it
noticbly slower so I dropped it and went with separate queries for
when genres were and weren't present.

You've done more than I have. All I've done is think about it
occasionally. The two list approach is where we left it. Lately,
I've been considering an easier [to code] solution. That is to keep
the single list and add keybindings to make navigating the list box
easier. For example, Left and Right would move to the previous and
next major grouping, respectively. 0 through 9 would move to that
percentage times 10 in the list.

At this point, I'd probably keep the existing (or patched as attached)
category search. The multiple genre search would be a separate menu
entry. Users of xmltv grabbers would quickly learn (or a popup could
tell them :) that that functionality was not available to them.
