ATI MMC doesn't really cut it clearity wise even if it does a great job on deinterlace. I was messing around with DScaler a bit but it doesn't really support it so I had quite a few issues before my computer crashed. I was able to get video when it was on unknown source. However, when I switched it to the ATI source itself, I only had sound. I'm currently using virtualdub, but the deinterlacing is rather insufficent. The video clarity is really clear compared to the other 2 though.
