Wait, the user might not know the correct technical terminology. For example, DVDrip and PyD are not the same, but sometimes used interchangeably. I should clarify the difference: DVDrip refers to extracting from a DVD disc, while PyD is a standard for encoding. Also, x264 is a codec, and DD 2.0 refers to Dolby Digital audio with two channels. The 320 kbps bitrate for audio is standard, so that's good quality.
