Don't accept PCM audio on your DVDs. Dolby Digital AC-3 audio sounds just as great as PCM, but takes up only 1/8th of the space on a 2-hour movie. The extra room allows for a higher bit rate encoding of your video. The higher bit rate means there is less compression used to fit your video onto the DVD giving you a higher quality. HomeMovie.Com has always use Dolby Digital AC-3 audio encoding on its DVDs giving you the best quality available.
