Thank you Dann, this answer my morale back. 
I read very bad reviews about the design of Passion-xbmc (my forum) on-top sites. I would never read this kind of thing. And I want my members like the site design. I think you can help me.
I spent many hours on the internet to search SMF'Themes. Here we find the most beautiful.
As Dice previously suggested, your best chance would be to download a free theme from DS for test purposes. Bikken has coded his themes in a similar and organized way, which shortens the odds and further chances of getting critical errors between one another. From all of his, Urban is indeed one of the few ones that has required more coding, hence the chance of it reacting differently to your Mods. I still do, however, think that your mods will not stand as unsolved problems as I am pretty sure that Bikken, maYday, antechius and Kethra have the knowledge and will to support and help fix any upcoming necessity.
That is how and why DzinerStudio outsmarts and out stands as much in the Theme scene.
Good luck,
Dann
