Description Sergey Svishchev 2007-07-22 04:21:49 UTC
Xvideo output from mplayer and xine looks as if it was downscaled in half and then upscaled back.  The card has ATI Rage II+DVD chip.

Might be a chip limitation or the overlay set up wrongly, hard to tell. You could try mplayer's vidix output and see if it looks any better if not maybe the hardware can't do better (or the vidix driver just has the same bugs, which wouldn't be unlikely...). I think those mach64 have all sorts of strange limitations if it comes to setting up the overlay (depending on source resolution, destination resolution and certainly depending on what type of mach64 - there are lots of slightly different chips around...). Does it looks "bad" regardless of the source video resolution?

Yeah, from 320x240 and up.  I don't have videos with lower resolution at hand.

I no longer use this card, but can test patches if they ever become available.

Cosing as WONTFIX due to age.  If you find a solution, we can merge a patch.
