¿Acaso no es molesto cuando bajas unos subtítulos y resulta que no están sincronizados con el video?, ésto pasa muy seguido cuando bajas películas de internet, ayer no podía ver el OVA 2 de Rurouni Kenshin por éste motivo, así que decidí hacer un script para hacer desplazamientos de tiempo en la pista de subtítulos.

¿Cómo usarlo?
