[MPlayer-users] tdfxfb scaling bug

First I want to say that I __HAVE__ been RTFMing last
4 days. I have been also looking at the sources for
hours, trying to locate the problem, but I can't. 

The problem: when using tdfxfb as output driver, it
must scale the image (when -fs or -xy 640 for example
are used). And this must be hardware scaling. BUT when
I see the upscaled image, it appears less than
optimal. For example **on the same machine, same
resolution, same movie** when I use -vo xv,
everything's alright. The scaling is perfekt, but when
I look at tdfxfb's output, I have the impression that
the image is scaled by cheap software method. Of
course this is not the case, because SwScaler stays
turned off and everything's done by the tdfxfb driver.

This is _very_ important thing to fix, because not
everybody can see it and I think that it IS a bug.
Just compare tdfxfb and xv output when upscalling
small, say, 300x200 image to 640x480 and then xv's
