but it would be maybe even much better if you could put the $trailer
in DB for "filename" instead of $localTrailer, and let mplayer stream
all *.mov files instead of downloading all before someone even knows
whether s/he wants to watch it.
mplayer or a shell script with mplayer command could cache trailers
and save them for the further watching. but this is more complicated
than your script and I even do not know whether "filename" can contain
absolute paths. this would probably be a "misuse" of this field.
