I used to use a tube TV which had Component video inputs (still have it,
but going to sell it soon when I get my act together) and an Audio
Authority 9A60. The TV supported 480i/p and 1080i, though I had a
bear of a time finding a working mode.
Here's what I did:
-- NVidia FX 5200 w/2 outputs, one DVI and one VGA.
-- Tube TV is an AdventTV 32" HDTV model.
-- Using NVidia proprietary drivers.
-- 1280x960 32-bit color buffer.
-- One putting out 1280x960 @ 75 Hz.
-- One putting out 1280x960 interlaced using this modeline:
ModeLine "1280x960hdtv" 54.540 1280 1424 1480 1616 960 1016 1032 1124 interlace +hsync +vsync
NOTE: I first tried a 480p mode with no lasting success (it would glitch
regularly, looked like a sync issue), and only after some experimentation
got the 960 interlaced line above working stably.
