I don't know about the software revisions...Suntan would probably be able to help you there.
I do have one question - does any universal remote work with this? I'm on the road again, and, well, I brought the USDigital box with me, hoping to snag some digital TV on the road. But I...umm...left the remote at home. (urp!) And of course, this box doesn't do squat without a remote.
I have even tried the Nevo remote program that comes with my iPaq 2215, and I can't get any codes working with it so far. It doesn't list Hisense (the manufacturer) in anywhere except the TV section of the downloads, and none of those 20 codes work with it.
Going to do some exploring. I might even buy another box and then move the second box into the bedroom or something...but I'm hoping to avoid that. If I can't get a universal remote to work with it, I'll likely just box it up until I go back home
