ok, now that this bug is in my head.... i set about looking for this information and lo and behold it isnt easy to glean by any means that I could tell.
So i started making a list, then realized the answer is already in the mythWiki it seems http://www.mythtv.org/wiki/index.php/HD_Playback_Reports#User_Reported_Data
Which brings up another question. Theres a script on that page that people can use to generate a report on their system playback details. Is there anyway we could integrate this into lmce...maybe something in the initial install that reports it back to a database? Over my head @ the moment seeing as how im still learning c, but just an idea. Maybe one of the devs could look into that one.
Also, i have no idea what the lmce requirements would be 'on top' of the requirements to play Hi def content? im not talking on a media director, but a core/hybrid situation.
sorry we got off on the wrong foot, and your point about the information being hard to find is taken. i still stand by my 'use the search!' statement but i can see how endlessly going through threads for clues isnt the best way to organize info. Hopefully the myth page i linked above will help you make your decision.
