BUGS

If first 4 bytes of MPEG file are 'RIFF' (I have a such file ;), then the file is incorrectly detected as AVI, and error is reported. This is actually bug in Video::Info::Magic perl module.

Not all MPEG files are detected as MPEG files. And sometimes error 'Strange number of packets!' is reported. These bugs are inherited from Video::Info::MPEG perl module.

OGM and RealPlayer formats are unsupported.
