Bitstream of PCM on my DVD player


When I setup my DVD player should I have it set to Bitstream or PCM, which is better, and what is the difference? Thanks again

Bitstream if you want to send the digital signal to a digital preamp and want to get Dolby Digital and DTS.
I have both connected. I use bitstream, as mentioned, for movies, to get full 5.1 surround. But I have found that many DVD concert videos sound better in 2 channel using PCM, than Dolby Digital.
I had the same question.
I have a Panasonic RP-82 that can do the decoding, right now I'm connecting it directly to the TV via a couple of RCA's, so, should I set it up PCM or Bitstream ?
