I finally had time today to set up the Mini and I scanned in about half the arc. So far the receiver is looking pretty nice! The menus are quick to respond and I was pretty much familiar with the structure from previous Ali receivers such as the Openbox line. Picture looks fine and sound is fine as far as I can tell -- I have to wait til I find a channel that I know has Dolby 5.1 audio though because so far all the channels that I've found with Dolby are only registering as 2.0, so I need to figure out whether they're really broadcasting that way, or if it's user error, or a bug. But the audio sync is dead-on on both Dolby and PCM channels, video is always in the correct aspect ratio no matter what format it is, and so on. (It did scan in one encrypted channel when it should've only been scanning FTA channels, but I'm thinking maybe it's an encryption type the box doesn't know or a mis-flagged channel because I'd never seen the channel before. It's a whole lot better than the Alien series polluting the channel list with BISS channels!)
I haven't tried recording yet because I have to reclaim my drive from the A3, copy whatever files I want to keep, and find my USB enclosure. That'll be a project for when I have more free time...
Looks like the Mini will become my full-time receiver since it doesn't have any show-stopping issues. Thanks again Michael for the contest!
