I can reproduce your problem, and I don't know exactly what's causing
it. However, I'm not sure it should be legal to let rve continue when
the movie changes.

When rve is initially invoked, it must know the width/height of the
movie, because out-of-bounds bitmaps will either crash mplayer or look
wrong. However, skipping to the next file in the playlist may change the
width and height, and thus rve should be restarted. The only case where
rve should be allowed to continue on a different file is when it's
exactly the same size and the chosen rve command repaints the entire
screen every frame.

For my own application the script that drives rve restarts it every time
a new file is played. Maybe you need to write such a script too?
