Are you sure this is a coaxial-digital cable and not a Subwoofer cable?

To prevent ground-loops, subwoofer cables often have the shield DISCONNECTED at one end and they have little arrows pointing in the direction of the sub.

Coaxial-Digital cables are simply Video cables and should have the shield connected at both ends. Video/Coaxial Digital cables are also all made with something called "75 ohm Coax". But subwoofer cables can be made with any of the popular coax types: 50, 75, 110, 300.

So check the cable to make sure it's a video/coaxial-digital cable. Even the wrong cable will appear to work, but people have noticed audio drop-outs every few minutes with the wrong cable.

I think I noticed that on mine also. I can't check right now but I'll let you know later. I believe the arrows are going to the receiver.

In general, the arrow would point in the direction that the signal is going. In your case, from the DVD player to the receiver. But whether it makes any difference (except in the case that Bob pointed out) is a matter of debate.

Coax cables can have the same directionality as other audio cables, though it seems to be less common on digital cables. As Steve notes, the arrows should point from the source to the receiver/amp.
