Xinerama with analog TFT & HDTV TV

[mic64]

Hi

xorg is driving me crazy..I´m trying now since days
to get the following config running.
-HDTV DLP TV on DVI with 1280x720p at 60Hz
-TFT on VGA with 1280x1024 with 60Hz

with the following xorg.conf I get the HDTV DLP with 1280*720, but the TFT is blank.
The Output on the HDTV DLP looks kind a stretched, but at least its something.

Error code from xorg.log

Anyone an idea how to get this to work?
