I have set up this amp using the auto set up but now when it is in the dolby digital mode the voices are extremely low. The sound overall is good but you can't hear the voices very well both when watching a tv show or a dvd.

The problem can be the cable or speakers or RX-V463 or settings. Need to check one by one.
Set the RX-V on DTS or Dolby Digital
1) Check Cables - connect the 2 (surround) cables from RXV's Centre Out to Centre speaker. If the Centre speaker works, then cables are ok.
2) Check speakers - Connect each Surround speaker to RXV's Centre out. If it works Speakers are ok.
3) Check RXV - Set it on DTS or Dolby Digital
Connect RXV's surround out (one at a time) L and R to the Centre speaker. If there is no sound, the problem could be RXV's settings (I need to read the manual).
Unless the TV has an output for Dolby Digital, you can only listen in stereo or a pro-logic modes, or other none digital mode. If you only connect 3 of the 5 speakers, then the other two channels will simply not be heard, but it shouldn't damage the amp.
You may have had the receiver set to "Stereo" mode, or Analog instead of "Digital" or "Auto" (automatically switches to digital when it detects a signal) modes. Also, setting it to "Direct" (2-channel from an analog source) could result in loss of center channel. Or your Surround Parameter dial (on the higher-end Denons, at least) could be set to a 2-channel mode. Finally, if your digital inputs are incorrectly assigned (e.g., COAX1 instead of OPT1, or OPT2 instead of OPT1) for that source, the receiver will use the Analog signal which is stereo-only. You could get a center channel via Dolby Pro Logic II but it would be a "matrixed" signal, not the "real" center channel you could get via digital input using Dolby Digital or DTS. (If all else fails, re-check your center channel speaker wire connections. It's very unlikely, but also possible, that either the receiver center channel amp or the speaker has failed.)
PCM mode will not output dobly digital, use the digital cable connection, not RCA cables, set DVD audio output menu to Dolby digital or DTS. On DVD software menu setup select audio then Dolby Digital 5.1 or Dolby Surround.
If you get sound on direct mode say from dvd but no sound when you go to dolby make sure you have the right input selected by pressing the digitat input button on the front of the amp,ie if dvd optical out is pluged into amp optical input 1 select this on amp then set audio to prologic2.DVDs through this input will decode to dolby digital/dts.
hope this helps.
Typically, only stereo inputs exist on any comsumer-grade receiver, and the actual decoding to 3, 4, 5, 6, and even 7.1 is done internal in the receiver. When a "placement" signal is detected by the receiver, the sound is routed to the correct speaker.Please refer to a user manual
set it on dolby digital mode not sterio mode should be differnt modes on a ch only use prologiic or spin the mode dial to doby digital on movie on direct tv wont be dobly fake suround more less but center should work change settings modes
