Then explain to me where the last frame went, mister. ;)

Without this patch, the (for example) Back To The Future chapters menu displays
a white frame - which is the last frame of the preceding transition movie
before arriving at the single video frame that constitutes the menu.

Pushing the last buffer makes it work... so, either the correct final frame
isn't being pushed, or it's not being rendered for another reason (like
timestamps going backward, or being discarded for QoS?)

Also, if this isn't correct - then the still frame event handling isn't either,
because it does the same thing.

Another thing that occurs to me - perhaps there's a discont buffer being pushed
here, in which case the deinterlacer might not be pushing it because it doesn't
have enough history.

It may be obvious how little I've actually read the deinterlacer frame handling
logic.
