Last year I bought a NeoTV 550 in order to play my ISOs through my home theater. Problem is that the device never worked right, even after latest firmware updates. Half the time it won't come on and has to be unplugged, which then corrupts the local databases that have to then be rebuilt. Now the front USB doesn't work right, in order to view videos I have to rebuild the database everytime, regardless of which hard drive I plug into the front (if plugged into the rear USB then the problem doesn't happen, drives are free of defects after scanning). Some blu-ray ISOs have improper audio. Network performance is horrible, it only has a 10/100 NIC that constantly flaps. So, I'm looking to toss this piece of junk and replace it with something new. In particular, I'm looking at the KDLINKS HD720 and HD700. My only real requirements are the ability to mount and play DVD and Blu-ray ISOs stored on a NAS (actually shares on my server) AND it must be able to bitstream audio over HDMI (pass thru). Does anyone have any experience with these players or maybe have another suggestion?
