A mi si me ha presentado problemas el vegas 11 bajo win8 pero solo en el render por lo demás me deja editar, tuve que migrar a vegas 12 y santo remedio, el vegas 12 no lo he probado en win7, y la PC mas chiquita donde eh instalado vegas 12 es una dual core Intel a 2 GHz, 2 Gb RAM, HDD de 320 Gb con tarjeta de video Nvidia de 512 Mb DDR3, tal vez también sea hora de migrar a win8...
Saludossssssssssss y suerteeeeeeeeeee
