* USING MPEG_LIB WITH THIS PLUGIN: mpeg_lib 1.2.1 can be found *
* at ftp://ftp.mni.mcgill.ca/pub/mpeg/ - however, mpeg_lib 1.2.x *
* contains a bug in end-of-stream reporting, which will cause it *
* to crash in conjunction with this plugin. I enclose a simple *
* patch below which fixes the problem (or at least the symptom.;))*
