I don't have the name of the program to hand (although I think I've posted it on here before), but there's a bit of software that takes an MKV and dumps the audio/video streams, untouched, into an MP4 container which will play perfectly on a PS3. Of course, it's not as convenient as downloading a file straight to a USB HDD and then plugging it straight into the Western Digital box, but it's only a little bit of extra faff.
Yeah, there are two; GotSent and MKV2VOB. You're right on all counts there. It's not an MP4 container, though, it's a VOB (which is deeply weird if you think about it, and putting a H.264 bitstream in a VOB violates all sorts of standards but for some reason the PS3 plays it).
You can't always do it untouched though. If the MKV has AAC audio in it (you often see that on US TV rips, though not often on movie ones), then unless your PS3->amp connection is over HDMI you almost certainly won't get surround sound. And some rips I've seen have AC3 soundtracks at bitrates that are higher than DVD support, which seems to drive my amp into a tizzy; I have to transcode those. And subtitles are a pain in the arse as the PS3 has no subtitle support (so they need to be "burned" into the video, so to speak).

360 owners are SOL, though.
Not quite true, GotSent has an "Xbox 360" preset. However it does some transcoding (I think), so it lowers quality and takes hours.

Incidentally, I'm rather intrigued by the media playing possibilities of the Acer Aspire Revo R3600L; it's a low-powered destop PC (kinda of the desktop equivalent of a netbook, in fact), but it has the nVidia ION chipset -- which the Linux version of XBMC natively supports for high-def playback. In other words, £150 and a little bit of playing with XBMC Live will result in a high-def XBMC box, which for me is pretty much the holy grail of media players. About the only thing it doesn't do is support infra-red remotes; I'm sure a bit of digging around the XBMC forums will come up with a solution to that, though.
That is a very nice idea! The remote problem is probably easiest solved with a Microsoft Media Centre remote and USB dongle? I'd be surprised if XBMC didn't support that.

Question! What are the best codecs? I'm currently backing up DVDs I own to MKV, because I lost my beloved DVD Shrink in the computay move. But! I am also backing up to 'highest quality' MP4, just in case. Which is right? There Will Be Blood somehow blew up to around 10gb, which isn't so workable in the grand scheme of things...
Those aren't codecs, they are containers. There's no one-size-fits-all solution to this because a lot depends on what you want to do with the files afterwards (where do you want to play them, mostly); however if you're making compressed backups that are bigger than the original DVD then it's definitely not the right answer!
For DVD backups I'd be tempted to go for vanilla Xvid or DivX in an AVI container, with the original DTS or AC3 soundtrack, and targetting 1.5-2Gb for a film. H.264 in an MP4 or MKV (possible with AAC audio) can give you better quality at smaller file sizes, but AVI files will play on a wide range of modern devices, like games consoles, these USB playback devices we're on about, even my TV (a Samsung) will play files from a USB drive.
