Help with Soft 15 kHz

[BigDaddyE]

Hey all, again, I hope that the community will be able to help me.

Though I would start a new thread for this one.

Here is what I have for CPU and hardware:

Biostar 890 GXB mobo
AMD Quadcore
ATI Radeon 4250 HD on board graphics
Catalyst
         Driver Packaging Version   8.70-100113a-095110C  
         2D Driver Version   6.14.10.7050  
         Direct3D Version   6.14.10.0728  
         OpenGL Version   6.14.10.9405  
         Catalyst™ Control Center Version   2010.0113.2208.39662  
Soft 15 - build 50
Nieman 24.5" CRT monitor
MAME 0.140

Long story on how I got here, private email me if you want more or check the Win7 64 thread I have on this board.

I have a stable picture running at 640 x 480, however, once I command line MAME in games, when MAME automatically switches the res, I get rolling screens or worse.

Once in MAME game, I adjust with vertical hold, which screws the desktop up, among other things.

I have attached a few pics of various games (Brubber, Lady Bug, Mappy, Mario Bros). I adjusted hold for Mappy (no reason, just the first one I picked).

Let me know what other info is needed, I will do my best to supply it.

Thank You very much.
