I was comparing two spec sheets:
	http://www.hauppauge.com/pages/products/data_pvr150.html
	http://www.hauppauge.com/html/wintvpvr250_datasheet.htm

Under chroma sampling, the specs say
  PVR150: YUV 4:2:2
  PVR250: YUV 4:2:0
Should that not give a distinct advantage to the 150?

All I know about chroma sampling is from reading
