That risks issues with network streaming and actually it already causes really bad issues with DVDs due to spinning down and the remaining 10% are not enough buffer to wait for spinup. > But, How can I change the code to get a better performance of mplayer's cache. The cache is doing it exactly what it is supposed to do, and what you propose would certainly significantly decrease its performance as a cache. So maybe you should explain what you want the cache to do it, since you consider it to be bad that it does exactly what is necessary for caching...
