I used the "1-Click Install" from:

So I'm not really sure what version it installs.  For the most part  
I'm using defaults of just about every setting.  Some people asked  
about the type of files I'm playing.  For now I'm just playing back  
what I have recorded with my HDHomeRuns ATSC tuners, from what I  
gather is MPEG2ts.  At some point I would love to be able to play my  
Blu-Ray disks, but for now I just want to get rid of my deathly TiVo  
subscriptions($50+ per month and now they don't let you FF through  
some commercials, f that).  I'm trying to use the Wiki as much as I  
can but damn that thing sucks for someone reading at a 2nd-3rd grade
