qt-faststart with dd did the trick.

On a side note, I initially tried to make qt-faststart on Windows in
cygwin, however, I kept getting this error "make: *** No rule to make
target `tools/qt-faststart'.  Stop." But when I did the identical think on
ubuntu it worked perfectly. I'm not that good with scripts so I'm not
exactly sure how to debug this. But I did run configure successfully in
cygwin. But it's not that important.
