Since my last message, I rebuilt mplayer & ffmpeg from svn trunk; after
twiddling some options, I got playback working. The only snag is that audio
gets downmixed to stereo. I next need to at least transcode the audio to AC3
so mplayer can spew that out a S/PDIF jack for multichannel playback. I might
also transcode the video to H.264 while I'm at it (haven't checked my other
discs yet, but the Caddyshack HD-DVD uses VC-1).
Some sort of live AC3 encoding, whether in software or hardware, would sidestep
this problem. I'd swear I've run across references to soundcards that do live
AC3 encoding before, but I don't recall any manufacturer or model information.
While searching, I found this:
Using this would require rebuilding MythTV and mplayer with JACK support, but
it should allow transcoding audio to any space-efficient codec you want (like
Vorbis or AAC) and converting it to AC3 on the fly. I might have to look into

My understanding is that Blu-Ray has another DRM scheme available to it, BD+.
DumpHD doesn't handle that, so it won't decrypt discs that use it. It'll only
handle Blu-Ray discs that use AACS (or that use no DRM at all, but then you
could just copy files directly from the disc).
