Yes, you can have it auto-login for you. Create a single user account and don't assign it a password. There may be another checkbox to tick to explicitly tell it to auto-login, but I think if you do those two things, it will auto-login.
The only other tweak in that regard is that under the power settings in Control Panel, you would want to tell it to not ask the user to login when awaking from Standby mode. I think that by default it goes into Standby mode after about 15 minutes of non-use. I configured it so that the power button will put the Revo in/out of Standby mode, rather than powering down. I couldn't get wake-on-USB to work for me to awake it by using the remote control, so I'm not sure if that's possible. But I think the way I've got it configured is perfectly acceptable. I've got it set to go into Standby mode automatically, and a quick press of the power button will bring it out of that state. Standby mode will draw a little bit of power, but even when running I believe this is considered to be a low-power box. Alternatively, you could set it to never go into Standby mode, so it's always-on. I haven't looked into it, but you could probably have it go into Hibernate mode automatically after xx minutes and then the power button would awake it from that. That would consume no power when "hibernated" but would take a little longer to awake. Honestly, though, even from completely powered down, the bootup time is very quick. I will time it later and report back.
As for starting up XBMC automatically...yes, you can simply drag and drop the XBMC icon into your Startup folder within the Start menu. I believe that there are other ways to do this as well, and someone here can perhaps explain the pros/cons of different approaches. I haven't done this yet because I'm still configuring things, but once I thing I've got things working the way I want them, I will definitely have mine start up XBMC automatically so that I can put the keyboard and mouse in a drawer.
On that note, if you expect to want to use the keyboard/mouse frequently, you might also want to consider buying a Microsoft Media Center Keyboard (about $30) which is a wireless keyboard that is compatible with the MCE-compatible USB IR receivers. I have one and it's not bad. It's infrared, so it needs a line-of-sight to the IR receiver, and I'm not sure what the maximum distance away you can effectively use it. It has a rubber joystick designed to be used with your right thumb as a mouse, and that's the worst part about it, but it works in a pinch. Or you could supplement it with a wireless mouse.
As for my .ISO problems with MPC-HC, I think I'm going to table that for a while. All of my DVD rips are .ISO files, but it looks like XBMC will play those fine with its native video player (presumably using the Atom CPU, since XBMC's player isn't optimized for the ION GPU yet). I hadn't really started ripping Blu-rays yet, other than for testing purposes, so I guess I'll just have to rip to a single .ts or .mkv file. I suppose I could also tinker with the PowerDVD 8 that comes with the Revo, but I don't think I was able to get 5.1 audio working with that and I think that the keyboard controls are all locked down (with MPC-HC you can reconfigure the keys to match up with what XBMC's built-in player uses for fast forward, rewind, pause, etc.).
So, assuming that I go with the approach of ripping to a single .ts or .mkv file, I now need to play around with the various tools to figure out which one seems like the simplest/best/fastest tool. I believe I've used Clown_BD and/or tsRemuxeR, and I've also heard about MakeMKV. I know that I've asked this before (and already received some feedback), but I'd love to hear more opinions about which tool I/we should use. The basic needs/desires are:
- Compatible with the Revo (and, specifically, MPC-HC). This seems obvious, but what I mean here is that I don't particularly care if the resulting file will work on anything else, so if there's a tool and/or file format that is easy to use but only works on a handful of devices (including the Revo, of course), then that's fine with me.
- Ability to keep the Dolby TrueHD soundtrack (since MPC-HC appears to be able to decode it and send it over HDMI in 5.1) or at least convert this soundtrack to something of equal quality which can be processed by my A/V receiver.
- Ability to compress the video (and ideally still keep the Dolby TrueHD soundtrack or soundtrack of equal quality).
- DTS-HD??? Based on what little I know, it sounds like no players can decode or bitstream DTS-HD, so this always needs to be converted (or, more accurately, I believe that the core (lossy) DTS soundtrack gets extracted).
I'd much rather watch a great movie in B&W at 240 lines of resolution than a lousy movie in 1080p with lossless audio.
