What are you taking about? I just watched "Ray" last week with MPC-HC.
OP, don't listen to this guy. Do the steps in the first post for MPC-HC Advanced setup found in this forum and watch any bluray AND HD-DVD you want.The only thing you have to do is find the two biggest evo files (for hd-dvd) and figure out which one goes first by watching it to see if it starts out in the middle of the movie or the beginning of the movie.
To queue the second one up, hold your left mouse button down while selecting both of the biggest evo files. You might have to go bottom to top to get them selected in the right order.
I really can't believe someone would tell you that they don't play with mpc.
As for that posting, it should be noted that there is a 50+ page thread in this forum about people getting around Cinevia or SVP with blu-ray or the many other things that mpc-hc is capable of. Don't post ignorant S+!@.
