I think the slots thing is just okay. Slots put up in your face in advertising for nubies kind of gets in the way of just getting familiar with the receiver.
Matter of fact OpenATV 6.3 sits in slot 1 of my Mio and Vix in slot 2. I haven't fired up Vix in a long time now.
Another matter for fact is if I could easily trash the other 2 slots and recover internal storage that may make the receiver work more slick, I would. I saw notes of telnet commands of how to do it.
I guess having 2 slots with one set aside for a spare in case things go south with the primary one (like a botched update) is cool.
And the resolution/screen roll thing. Interesting stuff about your TV's capabilities in the Mio remote.

I know my older Sony projection looks like what is in the video. Sometimes it wouldn't play nice with my cable box.
HDMI was funky at times. I tried an HDMI>Component video adapter and those problems went away. Although only 720p res.
Neither newer Sony's have acted up. Handshaking got perfected I guess.
It's funny. I read of the screen roll thing and immediately though about the older Sony. Then I saw it!
Me: I'd say put slots and figuring out multiboot aside for now and just try to learn the box and firmware on it. Enigma 2 is pretty much the same aside all of the bells and whistles each version offers.
