[mythtv-users] Xbox overscan work around

[Dennis Cartier]

Hello,

I pleased to say that Derek Watson has found a usable workaround for the 
over scan issue with the xbox. As Derek mentioned a few days ago, you 
can use xbv to alter the over scan, but you have to disable double 
buffering to get decent frame rates after doing this.

To use this method, edit the /root/.xinitrc file contained in myth.tgz 
be as follows:

=====.xinitrc=====

xset -dpms s off &
#irxevent &
/usr/bin/X11/xmodmap ~/.xmodmaprc &
/usr/local/bin/mythfrontend &
xbv -auto 640 480 6.0 6.0
xvattr -a XV_DOUBLE_BUFFER -v 0
blackbox

======end=========

You can alter the last 2 parameters of the xbv command (6.0 and 6.0) to 
adjust the horizontal and vertical over scan to suit your particular needs.

Please note, you may getting some minor tearing in the video stream when 
running in single buffered mode, but it is trivial compared to those big 
black borders.

I still plan on releasing another version based on Xebian 1.0 to 
accommodate version 1.5+ xboxes as well as HDTV. I am also planning on 
experimenting with QT-embedded to eliminate X11 all together.
