Poking around in firmware 1.04.10_V for the TV Live, I noticed that there’s a /swf directory. In this directory are two interestingly-named files: freestream.swf and HuluTV.swf.
I’m by no means saying that there is hidden Hulu functionality in the TV Live - in fact, I am explicitly not saying this. But I don’t recall seeing this directory in earlier firmware releases (though I’ll admit it’s been a while since I’ve looked), and the filenames certainly are interesting.
If someone motivated enough to check the 1.04.10_B firmware for the Live Plus could kindly do so, I’d be interested to hear what crops up.
