Re: [mythtv-users] blue and red channel swapped with internal player</DIV>
<DIV><BR></DIV>Yes, It's a bug in the ATI drivers. There's a hack that you
could use to get rid of the problem. It didn't work for me,
though..<BR>Here's a quote from the MythTV-talk forums: <BR>---<BR><SPAN
class=postbody>You need to recompile with
USE_ATI_PROPRIETARY_DRIVER_XVIDEO_HACK enabled <BR>See: <A

target=_blank
rel=nofollow>http://svn.mythtv.org/trac/browser/branches/release-0-20-fixes/mythtv/libs/libmythtv/videoout_xv.cpp#L67</A>
<BR>Also you may need to modify this function to include your Xv adaptor:

don't think this will be fixed in MythTv so the only option is to bug ATI
to fix their drivers. I'm personally probably going to just <BR>get rid of
my ATI card and try NVidia. <BR><SPAN class=postbody><BR></SPAN><BR>Alex
