Today, I setup my recently purchased Toshiba PVR/DVD recorder (RD-XS32). It offers a wide combination of video bit rates and three audio bit rates (all 2-channel). The audio bit rates are for Dolby Digital at 192 and 384 Kbps and PCM for uncompressed recording. I'm planning on using it to record a variety of movies (TCM, etc) and music (PBS, etc). I'm thinking that for most non-musical movies, the "M1" setting of 192Kbps would be sufficient, whereas I'll probably use the "M2" setting of 384Kbps for musicals. For concerts, where music is obviously the sole focus, I plan to use the "LPCM" setting and select a low enough video bit rate to accomodate it. But I'm wondering what the normal audio bit rate is on pre-recorded DVDs. No, I'm not looking to dub prerecorded movies, but I'd like to maximize audio quality depending on the nature of the program being recorded, and I'm curious what the "normal" audio bit rate is on regular DVDs. Thanks in advance for any responses. Steve K.
