Planning to run both component and digital (DVI or HDMI) video cables through a long narrow channel in my walls (speaker and 12v cable already routed in the same channel). With limited space/ access I need to feed bare wire through the channel and then dress the cable and add the various connectors. So here is a list of questions I don't yet know the answer to: 1a. Can DVI or HDMI cable and connectors be bought for diy assembly? 1b. If so where, which cable spec etc? 1c. Has anyone done this already? (fyi I am in the electronics industry so ability, experience and access to solder and some crimping tools etc. will not be a problem but the size of HDMI might be a bit challenging unless the actual tooling is used!) 2a. Where can I buy Canare BNC or RCA connectors (planning to use Belden 1694A cable)? 2b. If one end needs to connect via RCA, is it better to terminate the cable with RCA or terminate with BNC and use a BNC-RCA adapter? After reading The Beekeeper's sticky I realise that only BNC is available in 75 Ohm and assume the BNC-RCA adapter will probably do nothing to help this limitation except future proof the cable for a BNC equipped device. 3. As there is already a 12v wire and speaker cable in the same channel will any of the cables be susceptible to noise/ interference? Thanks in advance for your help.
