This was pretty much how my system was set up until I realised
that16:9 DVDs (played using Xine) were appearing as letterbox on my
16:9 CRT TV, which didn't seem right. Not suprising though because
Xine must think the apect ration is 1.5:1 rather than the actual
1.77:1. So I tweaked the displaysize until the aspect ratio was
correct for my TV, while keeping the DPI as close to 100 as I could.
I suppose I should probably have adjust the resolution to an aspect
ratio of 16:9, but that was beyond my skill level.
