Телек подключен через HDMI. Работает VirtualBox. Стоят kde4. Как видно, памяти нет почти свободной. Но даже если отключить VirtualBox, высвободить память, в mplayer hdtv видео (1080p) подтормаживает, играет играет нормально, бах лаганет. И так повторяется. Пробовал разные vo, эффект тот же. Графические эффекты в kde выключал, не помогает. Помогите плиз. Так же Chrome сжирает много ресурсов. Выключил его. Показывает видео лучше, но есть такие небольшие неприятные проскоки, быстрее вроде видео идет чем надо.
