Subject: [Comm] Проблемы при просмотре HD ip-tv
Date: Sun, 03 Mar 2013 15:58:02 +0400
Message-ID: <51333ACA.2080702@gmail.com> (raw)

Доброго времени суток, сообщество!
Новый провайдер порадовал наличием в сети ip-tv.
При этом обнаружилась проблема - каналы в обычном разрешении показывает 
нормально, а вот HD каналы идут с заметными тормозами - картинка 
дергается и зависает.
Для просмотра используется vlc 2,0,1 система P6.
Загрузка ЦП при просмотре обычных каналов невелика и ЦП не поднимает 
частоту выше 1GHz

Если включить HD канал, то ЦП взлетает на максимальную частоту и 
загрузка тоже растет. И все равно тормозит.

Собственно вопрос - это уже железо пора на свалку или что-то в 
настройках надо старательно крутить?
