It has taken me a bit of time to get the source material aspect ratio corrected for video playing but I've now discovered that you can set user defined playback ratios in VLC Player. There are some standard ratios offered under the "Video" tab but to get user defined you need to run VLC from the command line.
So: In Windows hit Start and type "cmd" without the quotes into the search box then hit return.
In the command window you might see:
C:\Users\User>
At the prompt type "cd .."
to get up one level or type it again to get up to C:>
Then at the prompt type:
"C:\Program Files\VideoLAN\VLC\VLC.exe" --aspect-ratio=14:5
Exactly as above including the quotes. This will start VLC Player and when you select the video it will have the 14:5 aspect ratio needed for 240 line operation.
To display this you will need to download WinModelines from:
http://www.geocities.ws/podernixie/htpc/...ne-en.html
and copy the modelines.
For 405:
Modeline "664x377_25 10.1kHz 50.0Hz" 8.100 664 680 702 800 377 378 395 405 interlace +hsync -vsync
For 240 / 25:
Modeline "1200x220_25 6.0kHz 25.0Hz" 8.020 1200 1217 1291 1336 220 221 233 240 +hsync -vsync
and tick the "Composite" box for VGA2.
and hit "Save Changes" The PC will reboot to incorporate the changes.
Then in Control Panel, Display select the second window select the 1200x220 for 240 line.
The VGA output from your graphics card will need to be connected to your 240 line television via an appropriate modulator (e.g. Aurora with switch 6 selected) and you can now use your PC mouse to slide the VLC player off to the right side of your PC display and into your television display. To fill the screen you need to hit f on your keyboard whilst the mouse pointer is in the VLC window on your television screen. (Esc returns from full screen mode.)
The same procedure can be used for 405 lines but only requires a 20% increase in the aspect ratio width.
