This is the best "tweek" EVER for BTV. I went from having a choppy screen (using the newest Hauppauge drivers and Hardware acc on setting = good) to perfect pictures with great quality and sharpness (hardware acc on and setting = best on recording). This post should become a sticy !!!!!!!!!!!
For the record. I'm using FX5500 video card, Hauppauge PVR350, AMD 2400+ Mobile XP processor.
