Hi,
Last time I asked question about displaying 320x240 on
a VGA screen but instead of using the whole monitor
screen, I want to use a portion of the area at the center:

      1024x768 SVGA PC monitor
   +---------------------------------+
| 320x240 |
| --------------------- |
| | | |
| | | |
| | | |
| --------------------- |

There were a few solutions proposed in the last response, however,
since I have to output 8 channels, I might not have enough frame
buffer and create some blank channels to mask the border.
And I am thinking about using video format compiler (vfc),
any suggestion? By the way I am not familiar with vfc, is there
any vfo file that I can use?
Thank you in advance!
