A USB DVB-T2 tuner for a PC also bypasses the HDCP on the Freeview HD channels.

More accurately it bypasses the HDCP added to the HDMI output by official Freeview HD tuners (the HDCP is a licensing requirement).

If you buy a non-Freeview licensed HD DVB-T2 PVR you may well find :

1. The HDMI output doesn't have HDCP
2. The recordings made are unencrypted with DTCP (unlike Freeview HD licensed PVRs and TVs that record to external HDDs)

A PC tuner - either USB, PCI-e or Networked (like the HD Homerun) is another solution as you say.

All of the above also holds true for non-Freesat licensed satellite solutions.

This DVB-T2 receiver from August will also record to a USB stick. Amazon calling it a Freeview box when it isn't.

To be fair - it's probably Daffodil - the seller/supplier (or August, the manufacturer?) who wrote the advert, not Amazon.

Unless something is actually being sold (not just fulfilled) by Amazon, it's important to remember Amazon is kind of like eBay when it comes to third party sales (and product descriptions).

"Freeview HD" will only allow branding, and access to the EPG data if the output from the box is encrypted with HDCP, and USB recording is encrypted. The EPG data is encoded with a proprietary Huffman table, that you get access to by agreeing to the terms.
There is nothing to stop a manufacturer making a generic DVB-T2 box, without access to the Freeview HD EPG, like August do, and allow you to record unencrypted. Recording onto a PC, and using an external EPG, like XMLTV, or one of the Linux programmes that can decode the Freeview HD EPG, to record the transport stream to your hard drive, makes recording possible.. BUT bearing in mind, the Freeview HD MPEG4 streams are a little non-standard, with HE-AAC audio and p/i switching.

That changed a couple of years back as I have full HD EPG data using my non Freeview branded DVB-T2 tuner.

Chances are your receiver is using licensed Huffman code tables without a licence... The proprietary compression of the EPG is still in use last time I checked earlier this year.

(The tables were reverse engineered ages ago - they are similar to Freesat SD and HD tables AIUI)
