Adding modeline to monitor *replaces* modelines probed from DDC?!?

[Greg Stark]

I'm using Radeon MergedB and trying to figure out how to add a modeline just
for CRT2. 

What I really want to do is get tv-out working. I imagined that that required
getting NTSC timing for the analog VGA output which I imagined required adding
an NTSC modeline to the monitor on that output. Except I'm a bit confused
because there isn't really a monitor "on that output" there's just one Monitor
one Screen section attached to the Device and I'm unclear what significance it
has at all except as a placeholder.

In any case I added an NTSC modeline to the monitor and an NTSC mode to the
Screen. And added a 1920x1200+NTSC metamode. And weird things happened.

It seems "NTSC" is now being listed in the "established timing table" in the
DDC info. And it's *replacing* some of the standard timings that normally
appear there. This prevents it from starting up in 1920x1200-1600x1200 (since
it no longer recognizes 1920x1200 as a supported mode).


So my questions are:

1) How do I add NTSC as a mode for the monitor on CRT2, not CRT1.
2) Is there a bug here that standard modes are getting thrown out?
3) Is this the right way to go about getting tv-out working?

Actually from what I read online the tv-out works under windows even without
changing modes on the desktop. That would tend to imply there's a third "CRT3"
or something that controls the tv-out. Is that possible?
