-----------------------------------+----------------------------------------
 bswap_dbl() tries to swap two variables without saving one to a temporary
 variable, corrupting the value of the swapped double. This bug only occurs
 on big endian backends that need to use bswap_dbl. This bug causes several
 side effects: playback of the video works correctly but often emits lots
 of "NVP: Prebuffer wait timed out 10 times." messages, OSD messages will
 not fade away automatically, and nuvexport cannot export the files. I have
 attached a patch that fixes this bug.
