I am not a Win95 fan and I don't mind comparing two different
implementations which I did in my case thats all.

It appears that Hauppauge has implemented the "overlay" capability in
their driver. "overlay" in this case is direct dma transfer . Intel 
got lazy and didn't implement this feature in their driver actually
they only implemented yuv9 and rgb24.

	Have fun,
