Why does Crystal play few video files in different ways (positive or negative) unlike other players do?
Most players are just shells over Active Movie component – that's why they inherit all bugs and features implemented in standard Windows Media Player. CrystalPlayer goes another way – it uses DirectShor only for media decompression. CrystalPlayer has internal renderers and internal parsers for different formats (AVI, MPG, Real), internal filters and buffers.
