I am not saying that different cables will necessarilly stop information getting through but that they have an effect on the QUALITY of the signal, which is very, very important - slightly less so in computer applications because you are simply transferring data

First, I don't see how you make a distinction between digital data on a computer and digital data in a home theater. Both are just streams of data. If a 400 ft run of ethernet cable can transmit a stream of data faster than DD requires, why would there be any problems with a 3 ft run of sheiled co-ax?
There is no doubt that cables have an effect on the quality of the signal. However, the question that 1138 is posting is whether or not that difference throws the DD decoder.
Also, there was a website that ran a test about a year ago. They used a Dolby Digital decoder that returned the number of dropped bits. They used a multi-hundred dollar co-ax cable and pitted it against two coathangers with rca plugs soldered onto the ends.
The decoded showed no errors with either configuration.
Now this is beleivable. DD decoders should be robust enough to get all of the bits even if they aren't perfect square waves.
However, you are claiming that jitter now becomes a problem.
DVD players have a buffer on the player that's sole purpose is to accomidate for jitter from the pickup. Therefore the only jitter in the system should just be caused by the cable right?
However, this is still just an undecoded DD stream. Complete with time indexes and everything right? So what kind of difference would jitter in the cable make... assuming that the above assumption is true in that the decoder receives no errors.
I started thinking about this when Shane (tech-editor on this site) did a review on Camelot's dvd de-jitterer...
