All right, I changed the 1080 back to 540.  I thought that
might be possible.

However, this produces the following in my Xorg.0.log when I
try to start X at 1080i:
...
(II) VIA(0): ViaValidMode: Validating 1920x1080 (74250)
(II) VIA(0): ViaModePrimaryVGAValid
(II) VIA(0): VT1625ModeValid
(II) VIA(0): VT1622ModeIndex
(WW) VIA(0): width=640:1920, height=480:1080, std=1:6, name=640x480:1920x1080.
(WW) VIA(0): width=720:1920, height=480:1080, std=3:6, 
name=720x480Under:1920x1080.

(WW) VIA(0): width=720:1920, height=576:1080, std=2:6, 
name=720x576Over:1920x1080.
(WW) VIA(0): VT1622ModeIndex: Mode "1920x1080" not found in Table
(II) VIA(0): Mode "1920x1080" not supported by TV encoder.
...

The check in VT1622ModeIndex() checks height 1080 against 540,
which fails.  Should this search in the Table be doubling the Height
when TVType is 1080I?  Anyone know where the problem and what
the fix is?  How can I set xorg.conf to bring up 1920x1080i ?
Later on I'll let you know how the 1280x720P looks.
Thanks for your help.
