Question Unable to set TFT as first Screen with twinview

Hello!
I have a TFT (connected via DVI-D) and a CRT (connected via DVI-I) connected to my card (4600, Dual DVI).
Using twinview I only get the TFT running as the second monitor. Changing the position works like expected, so the problem seems to be minor. But now I am unable to watch (fullscreen and/or accelerated) videos on my TFT. Playing (e.g.) Quake3 works fine, though (I can choose the screen without changing the config).
I tried to fiddle around with "ConnectedMonitor" ("DFP, CRT", "DFP-0, CRT-1", ...) but can't find the right solution.
The README says:
1) fullscreen video (overlay) only works on the first display
2) (in notebook sektion) digital panel always is the second display
The best result I could get was:
- TFT is first display
- CRT is second display
- CRT gets 60Hz (TFT's setting)
- TFT should get 85Hz (CRT's setting) but only uses 60Hz (because auf DVI-D I guess), which is good

Here I have the problem that my CRT does not get the right refreshrate (1600x1200 @ 85Hz should be right).

Thanks for any help!

My specs:

Gainward Geforce 4 PowerPack! Golden Sample (Geforce 4 4600) with Dual DVI

Monitor 1 (TFT): NEC 2180UX-BK (running with 1600x1200 @ 60Hz)
Monitor 2 (CRT): Hyundai P910 (running with 1600x1200 @ 85Hz)

NVRM version: NVIDIA Linux x86 NVIDIA Kernel Module 1.0-5336 Wed Jan 14 18:29:26 PST 2004
GCC version: gcc version 3.3.2 20031218 (Gentoo Linux 3.3.2-r5, propolice-3.3-7)

XFree86: 4.3.0.1 (built on 2.6.2)
Distribution: Gentoo (stable, so without ~x86)

The important extract of my (workaround) XF86Config:
# configured screen is my TFT
Section "Device"
Identifier "My Video Card"

Option "SecondMonitorHorizSync" "30-108"
Option "SecondMonitorVertSync" "50-160"
Option "MetaModes" "1600x1200, 1600x1200; 1280x960, 1280x960; 1024x768, 1024x768; 800x600, 800x600; 640x480, 640x480; ,1600x1200; 1600x1200,"
Option "TwinViewOrientation" "RightOf"
#Option "ConnectedMonitor" "CRT-0, DFP-1"
Option "NoLogo" "1"
Option "DigitalVibrance" "0"
EndSection

According extract of XFree-log:

(**) NVIDIA(0): Validated modes for display device CRT-0:
(**) NVIDIA(0): Default mode "1600x1200": 162.0 MHz, 75.0 kHz, 60.0 Hz

(wrong, it is a TFT/DFP)

(**) NVIDIA(0): Validated modes for display device DFP-1:
(**) NVIDIA(0): Default mode "1600x1200": 202.5 MHz, 93.8 kHz, 75.0 Hz

(wrong, it is a CRT)
