I think you have to be patient. These are experimental test builds. I wouldn't advise installing them on someone else's system.
Eventually when this is stable enough it will be pushed into master. Eventually it will make it into stable builds - but this will take months.

Automatically switching between omxplayer and dvdplayer is something xbmc has no infrastructure for (you don't know the details of the stream until the player has opened the file).
So that is not going to be simple to achieve. (It would probably mean removing omxplayer, and creating an omxplayervideo/omxplayeraudio that is contolled by dvdplayer).

It is likely that using dvdplayer as the default player will be satifactory for most users (who never play raw Blu-Ray rips).

I've always used these builds for the RPi I built and setup for my brother and he's benefited from and appreciated a lot of the improvements that have been made already, which he wouldn't have got from the stable, at least not for a long time.

I imagine that selecting omxplayer/dvdplayer could to some extent be done by file extension (i.e. VOB files are always going to be DVD/MPEG-2) but for extensions where they doesn't work and which could contain h.264 or mpeg-4 or divx, then I think that mediainfo or similar could be used to extract the details of the file before deciding which player to use.

I'll try setting dvdplayer as default for now though and see if that causes any problems with the files my brother typically uses (he doesn't use Blu-Ray at all, other than a couple of .mkv rips I gave him and mostly only rips his DVD's and downloads SD files from iPlayer and other sources, as he's only running composite to a CRT TV).
