Both. It tries to play SD content but just it sits there forever saying "Please wait". And this is despite the documentation saying that it
can play .ts files - and if you dig into the detail it says that includes MPEG-2 video and MP3 audio (MP3 encompassing
both MPEG 1 and MPEG2, the latter being what SD .ts files contain).
HD content it refuses to even try (and yes, it is decrypted).
Also, the Humax doesn't offer content on its USB device via its DLNA server, so that's a big chunk of content I couldn't get at that way even if the TV could play it.
On the plus side, and contrary to what the documentation seems to imply, it turns out that the TV
can happily stream MP4 content directly from my NAS after all. So at least I don't have to go to the Roku every time for that.
For the sake of a tenner, surely it's worth a try?
If you mean the device linked from the article you quoted then that link is actually for a product on Amazon US. For some reason when I click on the link it gets munged into a search on Amazon UK to come up with a £9.99 box but that's
not the same device. The correct Amazon US link for the box recommended in the article is
this, which would be $30+ shipped from the US - and a whole heap of pain to return if it turned out not to work. I did find what appears to be a UK-based supplier
here, but that's £39 plus shipping, a total of £47 - more than 25% of the cost of a new 500GB PVR, which is straining the boundaries of acceptability somewhat.
What I did notice is that the ViewHD box is 1080p
not 4K*. I
think that may be a key factor in finding a box that will work with the Humax (something to do with older HDCP versions is my current guess) and I
think I may have found a 1080p device in the UK for a not-too-silly amount of cash (including a £1 off voucher until 5/12/22) that might do the trick. It's an audio extractor rather than an HDMI splitter/switch, but at least (a) it's easy to return if it doesn't work, and (b) there is some evidence both in the product listing/reviews and
elsewhere that it should/might work.
I'll keep you posted.
* Reviews of the 4K boxes that I looked at on Amazon UK (before I got bored) all seemed to suggest that the HDCP "bypass" functionality was pretty hit-and miss (and this is borne out by other sources such as this YouTube video). In my experience the 'descriptions' of most of the cheap stuff from China on Amazon and eBay are so detail-free as to be more or less useless.
