redfox ReClock

ReClock helps you get rid of choppy playback of video material (AVI, MKV, DVD, Blu-ray, etc.) on a PC or PC connected to a TV or projector. With the help of ReClock, you can watch PAL audio/video at the correct speed. You get the "best of both worlds": Enhanced PAL resolution with correct NTSC speed.

It can also fix the so-called PAL Speedup using the DirectShow filter, which is loaded instead of the default DirectSound audio renderer.
