I can not use advcfg.exe because it crashes while trying to test my configuration. Then I made a config file for advv.exe:

device_video_format 16000 0.7438 0.0433 0.0743 0.1384 0.9216 0.0048 0.0448 0.0288
device_video_clock 5-50 / 16 / 50
display_size 720

And tried creating the modeline using advv.exe. I press f5, and enter vsync:50, x res:720, y res: 576 and it creates such weird(not working) modeline:

device_video_modeline generate 15.36 720 768 832 960 295 296 311 320 -hsync -vsync

This cable needs positive hsync/vsync polarities; so i change it as
device_video_modeline generate 15.36 720 768 832 960 295 296 311 320 +hsync +vsync

Still no go.

As i stated in my previous post, i have the correct linux-compatible modeline in hand, taken from the cable instructions. It is:
"720x576" 15.125 720 762 834 968 576 579 607 625 interlace +hsync +vsync 

This is the modeline that surely works and i guess the only one that can work. I computed device_video_format setting from this modeline. But when I try to run advanceCD with the above config + the modeline:

device_video_format 16000 0.7438 0.0433 0.0743 0.1384 0.9216 0.0048 0.0448 0.0288
device_video_clock 5-50 / 16 / 50
device_video_modeline 720x576 15.125 720 762 834 968 576 579 607 625 interlace +hsync +vsync
display_size 720

I get "No video modes for your current configuration" error.

I suspect that my calculated device_video_format could be wrong; but i checked it many times. When calculating; I truncateded the float values to the nearest smaller value. For instance:
0.75324526  --> 0.7532

I don't think that it happens because it is not precious enough (I checked other preset modelines). The horizontal percentages sum up to 0.99998 something and vertical percentages to 1.

Thanks
