    Does DTS and/or DD 5.1 beat CD when it comes to sound quality?

    No, though it's probably not fair to compare a 5.1 track (DD/DTS) to Stereo (PCM, i.e. CD).
    Then again there are also poor sounding CDs and great sounding DVDs, so it might just depend on the title.
    I do enjoy the handfull of Music-DVDs I own though I have no CDs (same artist/title from the same master tape) to compare them to.

    Isn't the bandwidth use for DD/DTS greater than that used for PCM?

    44.1kHz 16bit PCM as on a CD is approx 1500kbit, 5.1 Dolby Digital on DVD is usually 448kbit and DTS is usually 768kbit (and occasionally 1500kbit). The data rate is meaningless on it's own since DD and DTS use different compression algorithms.
    For stereo, PCM is preferrable since it's uncompressed. Dolby Digital stereo is usually only 192kbit or less. There are no DTS stereo tracks released AFAIK.
    For multichannel DD and DTS it's mainly a case by case preference, a badly mastered DTS track could be worse than the DD track on the same disk and vice-versa.

    So all those who brag about their music DVDs being superior to the CD-version are simply wrong?

    Not necessarily. That's likely to be DVD-Audio, which is a separate format again from DD or DTS. That definitely is superior to CD, other things being equal. So is SACD.

    Non-DVD-Audio DVDs aren't necessarily restricted to Dolby Digital or DTS either, some music DVDs have 48kHz 16bit or even 96kHz 24bit PCM tracks.
