My $0.02....
Daniela's patch is wonderfully stable, and built on the very stable Eden 11.0 final. If your aim is just to get DTS-MA/TrueHD working with a minimal of fuss, then this is an excellent option, and kudo's to Daniela as I've said from post #2 here.
If you want the latest and greatest, and something where you can pull in new features as they come up, this patch isn't for you - it cannot be merged with any future release of XBMC as the base it is written on now includes AE as a core feature.
There are no stable 11.1's, 11.2's etc. As announced a while ago, the release model has changed. We merge features for 10 days of the month, and make fixes and prepare for the next merge cycle for the rest of the month. In theory, by the end of the month it's pretty stable - that's certainly the goal.
The bad news with that is the "stable" releases are 12.0 and so on, and those updates will come faster than the time between Dharma and Eden. The good news is it doesn't take a year or more to get new features like AE in. You are likely better grabbing an end-of-the-month nightly than after the first week of the month, but hey, if you have an issue you just get then next nights!
Troubleshooting is actually much easier with the nightlies. For one, AE has much better debugging logging. For another, the team always has recent code in front of them to diagnose with.
So to summarize: if this satisfies you then use it! It's very stable and does what it says on the tin. But you're stuck. If you want new features before 12.0 comes around, you have to go the other route, which you will sooner or later anyways
Personal choice, and there is no wrong answer!
Either way, I recommend at least removing the old XBMC folder (not your userdata / databases) and guisettings.xml before installing pre-Frodo XBMC,
