Andrew:  the quoted information below you mentioned is quite interesting so
thanks for passing it along.  I spent quite a bit of time reading some
forums when GG was working on bluray a couple of years ago and there is a
lot of confusion and inconsistency in the media AND the players.

Also, apparently you can burn so-called bd5/bd9 'formats' to usual DVD

I am still trying to decipher the below information you provided earlier.
Am I correct in stating that Mplayer could not play the udfs you created?
I do not have Mplayer installed on our laptop and am hesitant to put any
more unknown programs here.  You can just "ffplay bd.m2ts" in the bd_...
directory easily enough and the bd.udfs is that same bd.m2ts with all of
the requisite bluray formatting on it.  I do not know if Mplayer will play
the bd.udfs file directly.

... so I figured out testing some formally-present blue-ray support in

Also, you might like to download for Mplayer a freely-available file like
"Sintel..." from:
