I don't think you can fix the image centering apart from adjusting the
TV set (don't do it, there's high voltage in there). I think you may be
able to edit the OSD theme to move it around, but I've not tried it so I
don't know the details.

I doubt it. De-interlacing always compromises the picture quality, doing
it twice will probably make it worse. Since your TV-out is 50Hz
interlaced and you TV-set is 100Hz (interlaced?) you will have to have a
deinterlacer of some sort. I think the only way to not have motion smear
is to have MythTV use onefield de-interlace. But then you lose half the
vertical resolution. It won't get any better with LCD/plasma/OLED either
since they're all progressive technologies and the broadcast stuff looks
like sticking with interlaced. Anyone know if projectors can do interlaced?

Cheers,
