Hi All,

I have problem while playing movie with AC3 (SPDIF), evry time when i switch to ac3 sound, I have choppy frame and sound,

It happening only with AC3,playing movies with regular stereo it ok, it also showing the same symptoms when i useing Media player classic and Media palyer 11, my cpu usage it 40-60% even less and the memory is 500M.

Someone have an idea what could be the problem????

Thanks,
Robbie
