My dvd player can either sit under my projector or at front under the screen. This means I could have a short cable length connection for the picture (DVI) but a long coaxial 75ohm SPDIF connection to the amplifier. OR If the other way round the SPDIF can be short & the DVI cable would have to be long. Which is the lesser of the 2 evils? ie which suffers the most over length? many thanks for any input?
