Possibly but I don't think it is the network (I have a gigabit cat6) or usb. If I use the same usb hdd on my fast home computer everything plays fine. Same with the networked NAS.

It also plays some blurays just fine. Like I said I haven't had a lot of time to troubleshoot it could be some settings. It's a perfect box for all audio, dvds, and mkvs. Not so great for blurays. My opinion. The new one might be better. Not sure. I agree a little stutter is too much.

Another possibility is something is getting lost in the HDMI pass thru with my receiver since the REVO goes through it which uses HDMI to the TV. I haven't tried plugging the REVO straight into the TV to test.
