can you tel the dvd player brand?
or are you asking this as a general question?.
IME,if the dvd player has dolby,dts compatibility,yes you can connect it to a A/V reciever with either a optical or coaxial cable and benefit from 5.1 surround sound.
hopes this makes sense.
The coaxial digital out is considered to be better than optical, and will give you full 5.1 surround sound to be decoded by the AVR. Do not worry about DTS decoding. If you connect via coaxial digit, the DVD will send the data is 'raw' format and the AVR will do the decoding.
Regarding VCD, almost all DVD players will play VCDs. The specifications may not mention VCD in particular. VCD is a comparatively simple format and all DVD players should be able to handle it. If you have not yet purchased the DVD player, just take a good quality VCD and try it before purchasing it.
Hey Venkat,just to clarify,as per my knowledge,i guess optical is one step ahead of the coax,as the signals are transferred as light instead of electrical signals right?
What i also know is optical is better for short interconnects,as they also tend to get weaker in the long run and are more prone to external hazards.
Or i might also be wrong.Just clarify.
First, actually optical is better for longer runs (say over 50 feet). But for connecting a source to a amp, the distances (at least in our homes) are around 6 feet max. For these lengths, coaxial or optical should theoretically give identical performances. Optical cables could also minimize RF noise as they are immune.
Some people say that a CD signal which is an electrical signal is converted to light and reconverted, leading to possible degradation. This may not be true as the signal being transmitted (PCM or bitstream) is sampled at low frequencies (44-48KHz) and thus are more immune to conversion hassles. .
The only issues with optical are it's fragile connections and higher price for the cable. A bit of dust in the connection point could affect the movement of the light beam. If you notice all optical connection points have a small dummy plug. This should always be plugged-in unless you are using an optical cable.
The general feeling in the market is the co-axial is preferable to optical. That is why I said, coaxial is 'considered' to be better. For all practical purposes (and short runs) there should be no difference at all.
