Hola!! XD (sorry for using spanish peoples :P)
OK ok i will answer his question in english and then talk to him in spanish :P :
You might need to check the option "use old uvw" when you apply the meshsmooth, if i am not wrong, the uvw gets slighlty modified when the new polys are created.

eyy XD Hola, yo tambien soy de argentina, muy bueno el avion y .. aprobechando que conosco gente que hace 3d aca podriamos hablar por msn ^^ si es que usas, mi msn/email es izzes222@hotmail.com

Pablo is right. Imagine the texture is "stuck" to the polygons. Once you apply meshsmooth the polygons shift location and thereby the texture shift location. Checking the "use old UVW" may help. Personally I prefer to texture map my aircraft after collapsing the subdivided mesh.

I ran into same problems recently and unfortunately Old Style Mapping doesn't help a lot. It just streches whole map in the same way those edges are streched now. Texture changes its position only when Old Style Mapping is on. Otherwiswe it sticks whereit should be.

It is because mesh is uvw unwrapped before smoothing, and those streches occur on edges where mesh is divided into different pieces in unwrap modifier. A lot of people here collapse mesh first and than unwrap, but I see advantages of not collapsing mesh. Just spent some time trying to deal with this problem yesterday.

Will let you know if I find any solution, but for now it looks as if it won't be an easy one.
