[vlc-devel] xv problems with new via cle266 chipset revision

we've been happily using vlc in xv mode with the via cle266
(unichrome) chipset and the unichrome.sf.net driver.
However we just got a new motherboard and the chipset revision of the
cle266 has been bumped from 17 to 18. This caused locks in X under xv so
we had to upgrade to x.org 6.8.2 and the latest unichrome (also
These fix the locks but the mpeg output is distored in vlc.
Output from all mpeg files is correct in xine and mplayer using xv,
however we're happy using vlc and don't intend to change. We really
could use some help working around this problem though.
The output of the mpeg movies (720x576 res, but AR 4:3) is badly skewed.
At the bottom of the vout there are 5 or 6 lines of flashing mostly
green but sometimes multi coloured junk. The rest of the display looks
as if it's been wrapped somewhere other than at the edges and perhaps
even rotated slightly, although that may just be me being confused.
I talked to the author of the unichrome driver about this and he
believes it's a problem in vlc's xv code. Our subsequent discovery that
xine and mplayer display properly seems to agree with this, although i'm
open to all suggestions.
This happens with both our older 8.4 test1 and the latest source release
tar from the website.
Can anybody help, please?
