I noticed is that it sometimes very difficult to replace a saa713x windows
driver. The Lifeview drive is not compatible with the Philips driver and
for some reason, a install doesnt replace it. I can imagine that this
also is the case when you try to replace lifeview to lifeview.
But i am not a windows expert...
