I've connected both my Humax PVR and Samsung TV to my network using the RJ45 port that each has, but the TV reports that there's no cable connected and the PVR just refuses to use the wired connection and just falls back to using it WiFi connection.
On both units, the RJ45 port is adjacent to the HDMI ports so I'm wondering if the cat5e cables I've used are getting affected by RF interference from the HDMI connections?

Interference scenario is unlikely, have you proved the cables work by connecting another device that has a known working Ethernet port?

Yes, both cables were previously used to connect my router to a BT OR modem and to connect my router to a switch that drives the rest of the Ethernet network.
The reason I suspected interference is that the TV aerial cable previously used with the TV kept dropping the Freeview signal, replacing it with a known good cable made no difference - the fix was to make my own aerial cable with shielded solid core coax, which suggested that the issue was being caused by interference by the adjacent HDMI ports/connectors, so wondering if shielded CAT 5e might be needed for the Ethernet connections?

It's generally better (where possible) to stop interference getting out rather than getting in... have you tried a better quality (or even just another) HDMI cable?

If you think its interference then moving an Ethernet device e.g. laptop to the location of the of the devices and testing there may help identify that.
What was the aerial cable made of before? All coax I've used has a solid core and metal braided outer.

IMHO There would have to be an extremely large amount of interference to stop the network connection negotiating even if dropped down to 10Mbps - I'd work back up the networking route with a laptop or similar to see where the networking gets to.

One possibility is that the Ethernet cables are crossover ones, which many devices won't care about but some devices do.

Normally the leads that go between a faceplate in the wall and your TV for both satellite and terrestrial are stranded core coax. Much the same way as the mains lead for an appliance is stranded but the fixed wiring in the walls is solid core.

I've since learned that the RF interference from an HDMI cable would be in the UHF frequency and so shouldn't affect a cat5e ethernet connection.
