A lot of DVD players do not output true Redbook even if you play a CD on them. If the player doesn't output true Redbook, some DAC's will not establish a digital lock. it is also the case that some DAC's will lock but will put out a distorted sound with static pops etc.
Many DVD players put out Yellow Book when playing back a CD. We found this to be true in the store when we tried putting high end DAC's on some of our DVD players, even expensive ones ($3500 etc.) and couldn't get a lock, or ended up with a really frightening sound that almost took out some tweeters.
