Before you start nut-picking on others, look at your own posts please and collect some information on the topic before you try to correct others. I never claimed that all DVDs contain PCM audio only that it can be found on such media. Just to repeat my point: PCM is supported in all kinds of hardware and software, it can be thought of as the lowest common denominator of audio formats.

No matter how bad I am, your swears and offenses will always tell more about yourself than me.
