It's worked well, but I'm running into problems with mythcommflag and the H.264 files I need. Also, I later on decided to create a dedicated front end in my exercise room - only to discover that I couldn't use Mythbuntu.

Should be able to use 0.28 on Mythbuntu, IIRC you just load Mythbuntu-control-center and select, read the warning, type in the override and good to go.

I actually use PLEX for media that I want to keep long term, so just moving all the recordings I want to keep and starting from scratch is an option.  But It would be nice to have the recordings available for the frontend machine.

Hey, 0.28 is working! (Not just mostly working). Plus in a few months (give or take a few years) it will be general release and master will be 0.29.

If you have time / effort best bet is to probably post some info of the problems you are having in 0.28 and get them fixed - the same problems probably exist in 0.27 anyway, I very much doubt there is intentional breakage in 0.28 of something that worked in 0.27.
