Between your Variax's VDI jack, the HD500's, and your digital cable, you're probably seeing essentially the same issue I did here with an older Variax: http://line6.com/support/thread/83687?tstart=30
Basically one of the 8 connections made by the pins in the VDI connectors is not making consistent electrical contact.
First thing I'd suggest is to try a different digital cable. For testing purposes, you can use a regular computer Ethernet cable. You'll definitely want the authentic "EtherCon" style VDI cable for live use, though, since it has physical reinforcement on both ends.
(No, the signal is not Ethernet - don't plug it into your computer or router; you'll fry something. VDI just uses the same shaped connector.)
