Forgot all about this over the holidays, sorry...
I don't have a PS3 so I don't know what I-player on the PS3 looks like, However Your link to the BBC site seems to show I-Player Big Screen, Which as far as I am aware is what the Humax is already using e.g. It looks like THIS as opposed to looking like THIS
No, I didn't post a link to the iPlayer. What I said was "It's the normal iPlayer URL,
but when accessed using the PS3 user agent". If you access the big screen page whilst spoofing the PS3 user agent you get the new iPlayer. I did post a link to a blog post with video of the new iPlayer so you can see it there.

As I mentioned a while ago, until somebody can provide a working link to the new interface version, not much we can do.
Again, it's the normal iPlayer URL,
but when accessed using the PS3 user agent.
I'd already tried this and confirmed it (in post #7). I can get the PS3 interface to load, but not video to playback (it buffers indefinitely). It doesn't use Flash, it's all HTML and presumably JS. However, this only tells you what Firefox can or can't do. I've not tried it on anything else as it's not going to tell us anything more useful, but it does tell us that the page is accessible via user agent spoofing.
If you do want to try it, use Firefox, install the 'User Agent Switcher' plugin and add the agent 'Mozilla/5.0 (PLAYSTATION 3; 3.55)'. Navigate to iPlayer (any link, you'll get redirected to the player anyway) then use the arrow keys to navigate and spacebar to select (this is because it's designed to be used with tv remotes etc). It doesn't look that great in FF, but it does when fullscreened on a big telly.
Here are screenshots:
That's everything I have.
