I’ve tried multiple .MKV files with either AAC or FLAC multichannel audio tracks and so far I’ve gotten none to play back properly. They either play in 2 channel, play for a few seconds and cut-out, the video stutters at pretty much a standstill (native 24p setting) or doesn’t play at all.
Please investigate and fix this problem ASAP. Needless to say proper audio playback is very important.
Also, I was quite surprised (and dissapointed) to find that the new player doesn’t support DVD/Blu-Ray Rom USB drives. Yes, I know most people use harddrives, but I still like to store my data on DVD-Rom (and the occasional Blu-Ray) and it would be nice to have the ability to read directly off the disk.
