I used this code http://bellet.info/XVideo/testxv.c to see what adaptors are present for my system. It shows
XvQueryAdaptors returned the following:

I checked out the Xv documentation. It shows that there is a video adaptor also supported. But my system aint showing it. Does this mean that my system cannot play video properly using Xv ?
