That was my point - you've been arguing that autodetecting the monitor's 
aspect ratio would give wrong results sometimes, and that was a case where 
autodetection would give you the wrong results - it *should* be 4:3 (like 
mplayer defaults to now) but if you tried to autodetect it you'd erroneously 
get close to 16:9 instead because of the strange resolution.  Hence your 
argument to default -monitoraspect to 4:3, which will provide correct results 
in cases like this.

Cheers,
Adam.
