como aumentar o cache de gravação!?

[Kenedy]

cd às vezes eu gravava no windowsxp em até 40x, porém tbém normalmente não utilizava a velocidade max( 32x ou 24 x), já dvd sempre deixava no automático que escolhia o máximo(até 12x), fiz os testes e constatei que para não dar pau tenho que gravar cd em até 24x e...dvd até 6x...
bom...ainda acho que tem algo a ver com o cache(ou buffer), sei lá...se alguém tiver uma solução!!!
Grato.

Provavelmente é, como já foi dito, uma combinação de ambas as coisas. Aumente o buffer de gravação no K3B para um valor que não dê problemas, nem comprometa o desempenho, e reduza as velocidades de gravação. A velocidade máxima de gravação de um determinado drive é em geral definida como se o CD ou DVD fosse ser lido no mesmo drive, o que não é seguro.

executei o k3b pelo terminal e...veja abaixo :
