Help - DMAME, AVGA, Rolling!!

[Santoro]

My first cab had Advancemame and a D9200.  Due to everyone's praise of the ArcadeVGA, I picked one up a while back along with a K7400 Arcade Monitor for my next cab.

I can't believe that people think this is easier than Advancemame!  The problem is that I cannot find a single setting on my horizontal hold that will keep all the games stable.  

Here is my config:
Dos 7
DMame .69
AdvanceMenu runnng at 320
ArcadeVGA
SB16

Amy I missing some step that everyone else knows?
Thanks!
