Directshow Solucionado Pero No Del Todo

[scorpionhack]

 Buenas:
tengo un programa hecho en visual Basic que reproduce archivos de internet introduciendo la url , pero hay un problema y es que los reproduce poco a poco , como puedo hacer para que se reproduzca seguido??.

GRACIAS

[[EX3]]

 Reproduces 'al paso' o cargas primero todo el video en memoria o en partes? Oviamente si no tienes todo el contenido del video o secciones considerables de este no podra reproducirlo fluidamente.

Salu2...
