Address -Wall warnings

VideoWindow::ExposeEvent wasn't being used correctly; it should be a
TQCustomEvent (although, the 3000 type is already being used for
forwarding XINE_PROGRESS_EVENT).

While the pts_per_smpls part never seemed to be encountered, it would
have resulted in a floating point exception as it's always 0.  Commented
out to leave a hint as to what the code should be doing.
