[mythtv-users] DVD-Audio

[Tim]

I'd like to be able to play DVD-A discs at full resolution on my MythTV
box (currently under construction).

Is this possible now? (I'm willing to consider proprietary software if
necessary)
If so, is there any special hardware I need (using external digital
receiver/amp)?
If not, is anybody working on it?
If nobody is working on it, what are the barriers? Patents? Encryption?
Should I pose this question somewhere else?

Thanks for your help.
