@pankov:
I have said that it's still buggy, especially the frame numbering is inaccurate or wrong, at the moment I feel to use it only for testing (I don't want to make backups with skipped frames or such things, as opposite MPEG2DEC2.DLL works perfect...).
As I heard lastly it uses only integer-SSE so don't worry K7 users, 3Dnow! is enough to work.
