I have had this machine for almost 2 months. Went to play Xfiles today, of course ran into troubles... got the newest firmware, the disk would then play but the audio was all static - using just HDMI cable. Swapped the cables over to use RCA for the audio and that seems to fix my sound problems.
I have Prince Caspian, didnt have troubles with that.
Wall-E I had to start in Spanish then flip it to English but it played no problems.
Over all, not a bad unit, just always have to ensure your disks will play.
The only glitch I have run into that bugs my wife is on Dirty Dancing, 2nd last scene (the whole "nobody puts Baby in a corner" scene), that one freezes and thats it, cant get past.
