MPlayer does not assume you have an NVidia card (and
neither does the message come from MPlayer, but from
libvdpau I guess, which being a project started by
NVidia has reasonable reason to assume you use NVidia
when it can't find any other working implementation).
It just tries all methods to output video it knows
about, with the most efficient ones first.
If the result of that auto-detection works for you
and you don't want to change actual behaviour (I think
everyone thought you wanted VDPAU to work) I see two options
1) Just ignore the messages from the probing
2) Figure out which VO it actually selects in the end
(I suspect xv) and specify that explicitly (e.g. -vo xv).
Same behaviour minus irrelevant messages.
