setting volume to 100% does not help, sound is terrible! mpeg files, .ts files, .vob files, stereo sound, spdif sound.... all stop'n'go stutters! 114 ver is playing well with my old comp. amd 64 3700+, but new one (amd 64, 6xcore, xp-sp3 and realtek HD audio) is impossible. any real ideas? MPC plays...
