Description rene van den Braken 2006-04-10 15:46:59 UTC 
When selecting a 1080i timing, and playing a video on XV
only a few lines at the top are show.

Problem is in:
radeon_video.c
line 2497: 
v_inc = (src_h << v_inc_shift) / drw_h

on 1080i v_inc_shift=21
if src_h = 1080
this will overflow to a negative integer, and give wrong results !

Possible fix

Does this patch fix it? It'll still break with 2048i, but oh well...

Patch pushed to the main xf86-video-ati git repository. Please reopen if it
doesn't work for you.
