Yes, but I can't promise ./configure will always find the XvMCNVIDIA
library first when you disable xvmcw. Right now I think it is the
first vendor library it looks for, but it also looks for the I810
and VIA libraries and the order it looks for them is basically by
current popularity. Sometimes all three are present on one system
and there is nothing in configure that looks at lspci or anything
like that to determine which card[s] is|are actually installed.
