I don't think a DVI-VGA(-component) adapter is a silver bullet; you
will still have to do modeline configuration.

Anyway, I have similar overscan problems with my FX5200 to a Toshiba
42H83 RPTV via DVI cable. I'm feeding it 960x540p, but my display is
essentially only giving me 856x480 pixels to see.

I've just started fiddling around with HTimings and VTimings and don't
have good values yet, but for now, I've just told Myth to use 856x480
pixels, offset by +56+32 pixels. (In the Settings / Appearance UI.)
