Got my Revue in Monday - plugged it in on Tuesday and played with it for about 2 hours. I didn't bother installing the Android 3.1 beta yet as I want to see what I've got first so I can see the difference. Here's what I did:
Step 1 - Install DLNA server on my fileserver... I went with mediatomb after reading a few user reviews and since there was a clean package for it in the repo
Step 2 - configure sources in DLNA server (this is the most cumbersome part so far... but not too bad)
Step 3 - plug in my Revue and finish the "First Run Setup." This involves adjusting the image on your screen, joining your network (I decided on wireless since I'm so far away from my computer room or TV room), specifying your TV so that the keyboard can control it, adding your STB (cable box which I did not include since my cable box is in the TV room), and finally running a system update which I assume brought it up to Android 2.1.
At this point I have a very usable device... surprisingly capable and able to play most of my video files from my DLNA server. I tried a few SD .avi files which all played flawlessly followed by some SD .ogm files which also played without issue. Next I tried some 720p mkv files with .264 + ac3 audio - those too played flawlessly with less than a second of pre?buffering before video actually started playing. Next was 720p video containing .264 + DTS audio - these files played but without audio for the most part. I had a couple files formatted this way that did play audio and I'm at a loss as to why those worked. Everything I've read says it shouldn't play DTS audio. Next I tried 1080p mkvs containing .264 + ac3 - these came very close to being playable but skipped every 20-30 seconds (I assume due to wireless bandwidth as I doubt it was a processing cycles issue since the working playback was smooth as butter.) Finally I tried 1080p mkvs containing .264 + DTS - surprisingly this played back smoothly but without sound and no skipping or stuttering. That's probably due to the complete dropping of the audio.
My flac didn't load at all, but it might be an issue with my mediatomb setup, I'll work on that when I get some time. Everything I've read says that it shouldn't work before updating to Android 3.1 beta. Flac support is included in the OS starting at 3.1. I don't have any mp3s to test on and didn't have time to encode any just for this test.
Photo viewing was flawless but you'd expect that to work after getting any video working. The slideshow worked like any typical slideshow would.
Youtube playback via the built in Youtube app was flawless - but I wish it was a little more friendly with fullscreening and resolution selection. The trackpad works fine, but can still be a little touchy when you're in a hurry. I was hoping for something more integrated like the Plex Youtube add-in.
Application selection is pretty abysmal on this device by default. The apps that are there are really pretty useless and the only things of use are the half-useful media player and Chrome browser. In fact, all the Youtube app really does is launch the Chrome browser at the Youtube page.
I'll be doing my Android 3.1 beta update over the next couple of days barring the release of 3.1 official in the immediate future. I just want to make sure I get as much of this working before I do any real tweaking so I can appreciate the update even more.
edit: Oh - I forgot to add... I've seen enough good stuff from this to go ahead and order another. Even with what I've got so far it's worth $99 in my opinion. The keyboard is also quite spiffy for this device.
