just hooked this up and here are some things
1) 1080p mkv from hfs+ partition is unwatchable, artifacting (<- spelling) all over, going to try 1080p mkv ntfs in the next few hours.
2) im using optical and i got dts and dd from spdif
3) will not play blu ray backups that have been converted to iso has to be .m2ts files. this sucks b/c i have backed up my collection but if i want to watch on this i have to un-iso them.
4) have a back up (superbad) with single hd audio stream, it will not play it b/c it cant down convert like powerdvd.
so far not to impressed with it, the mkv off hfs+ sucks, but if it works on ntfs oh well. and the non iso playback is going to probably make me return this unfourtinally.
p.s. this is probably a duh but i tried to hook up my external blu ray but its said unrecognizable usb device, so that is a no go .
