Rubbish. Don't go blaming the problem on DVI vs HDMI incompatibility. The problem is down to device/device compatibility and that applies equally to HDMI to HDMI devices and repeaters and switches.
HDMI is a basically superset of DVI-D, in the same way that HDMI 1.3 is a superset of HDMI 1.1 etc etc etc. Would you expect an HDMI 1.1 TV not to work with an HDMI 1.3 source? Apart from not getting the extra features of 1.3, you would expect it to work. The significant part is that HDCP was a mandatory part of the HDMI specification, with DVI it was an option. HDMI carries audio, DVI does not. Talking about B&O bolting on HDCP on to DVI makes it sound like a kludge, it is not; it is a perfectly legitimate and common protocol used on many video devices, even manufactured today.
If a DVI device supports HDCP and the standard video resolution and colour space (rather than just PC resoutions and colour space), then there is no reason not to expect a DVI-D display device to be fully compatible with the video side of an HDMI source. Humax say as much in their quick start guide.

Connecting the TV
1. TV with the HDMI connector
Fore the best picture quality...
2. TV with the DVI connector
For every good picture quality...
You will also require a RCA cable/Audio L/R
3. TV with a SCART connector

Nothing there about the HDR-FoxT2 being incompatible with DVI.
Also, from HDMI themselves...

“HDMI Org FAQ
Q. Is HDMI backward compatible with DVI (Digital Visual Interface)?
Yes, HDMI is fully backward compatible with DVI compliant devices. HDMI DTVs will display video received from existing DVI-equipped products, and DVI-equipped TVs will display video from HDMI sources. However, some older PCs with DVI are designed only to support computer monitors, not televisions. Consumers buying a PC with DVI should make sure that it specifically includes support for television formats and not just computer monitors.
Also, consumers may want to confirm that the DVI interface supports High-bandwidth Digital Content Protection (HDCP), as content that requires HDCP copy protection will require that both the HDMI and DVI devices support HDCP to properly view the video content.”
So a TV supporting standard video resolutions and supporting HDCP should be fully compatible with the video side of HDMI in the same way that an HDMI 1.0 device should support HDMI 1.3 or 1.4. You may not get all the features, but an HDMI source should detect what is available on the sink (display) and a adjust its feature set accordingly.
The reason why I am here...my Loewe Xelos SL DVI equipped TV is having exactly the same issues. Its known good with other HDMI/HDCP reliant sources from Meridian (DVD), Panasonic (DVD) and the Freeview HD trial box (Freeview HD) from about five years back.
I did have HDCP handshaking issues at the start when using the Meridian DVD player, but Meridian updated their firmware and LinnSight updated their firmware after collaboration between us all. The Panasonic DVD and Freeview HD trial box worked right from the start, as expected. Also, my initial cable was found to have an intermittent mechanical issue at the DVI end causing non optimal connection resulting in intermittent HDCP handshaking. This was resolved by using a cable with a Molex DVI connector. The cable in use is the replacement cable, although it has not been in use for a while so may have developed a fault. But it does work with the Panasonic DVD player; the Meridian DVD and Freeview HD trial box having long been disposed of.
The bit about YCbCr vs RGB is interesting. Im not sure if it is my problem as watching the TV via SCART when the HDMI/DVI cable is inserted results in a message flickering on the screen too fast to wholely read but basically says that the TV does not support HDCP, and I know 100% that it does. In addition, the HDR should use the information in the EDID to recognise that the source does not support YCbCr (which I know from Meridian DVD troubleshooting that my TV does not) and revert to RGB.
It would be highly disappointing (ie the otherwise excellent HDR will be returned) if Humax did enforce YCbCr on a sink. I believe that this would actually be against the HDMI specification (which a source is expected to support the lowest feature subset of the display/sink) which would technically make the HDR-FoxT2 not HDMI compliant.
Having only purchased the HDR on Saturday, I missed the download and I have yet to manually update to latest firmware, but from previous posts, I have little hope that this will resolve the issue. So for the time being, we can add the Loewe Xelos SL to the list of devices incompatible with the Humax HDR-FoxT2.
