Wow this is confusing.  Can someone lend a hand as to what steps I need to go through to set this up?  My specs:
Radeo 9000
27" ESA TV
S-Video connection
So I download/unzip AdvanceMame.  First I need to run advmame to generate a config file.  Done.  
Then I need to run svgawin /l to load the driver, correct?
Then I need to run advcfg to set the clock rates, correct?  This is where I have a problem.  I choose TV NTSC, then choose Generic - NTSC TV (USA).  Next screen I need to choose "centering".  I get three options.  Any of the optiosn leads me to an error message, "Calibration mode unsupported.  The video mode is incompatible with the monitor limitations."  
What am I doing wrong?  I thought the video card was supported (it seems to be in the list) and I thought any TV would work.  Any ideas?  
Thanks.
