[mythtv-users] TV Output

[Stephen Williams]

The modeline I supplied is for use with homebrew VGA to SCART
converters, these only work by getting the video card to output a
signal which is within the spec expected by your TV.

Commercial converters (such the Key Digital converter) are scan
converters, these scale and interpolate whatever VGA signal you send
them into a normal TV signal. As such it really shouldn't matter what
resolution you send them (well, they'll work but some resolutions will
produce better results I suppose), check to manual to see what the
valid modes are.

Since you're using a scan converter you won't be getting as high a
quality image as is possible from a homebrew converter, this is
because of the scaling and interpolation it's performing.
