Hi All, Thanks for reading. I'm trying to play a 3d mkv file from my mac, through a DVI, to the LG LW5600 3d tv. But when I hit the 3d enable on the tv, it only allows me to select 2d->3d, not the side by side option that is the file (it's greyed out). I want to play from the mac as the file is larger the 4gb, and for whatever reason, I'm unable to spit it (I've tried a number of mkv splitters, but none are working). Also, when I play the file on my mac, it is a side by side video (I tested using VLC). Any help / advice appreciated.
