Summary: Some MKV files don't play the sound, or don't paly at all. I'm sure more firmware updates will be in the future, but iomega keep pumping a new MediaPlayer out, just want you to spend more money, but not fixing the old one.
Summary: Even though it outputs 1080i or 720p through HDMI port or component, it DOES NOT read any Hi-Def format! It reads a lousy standard def format and upscale to HD. Thus, the final image is full of noise and artifacts. If you want to watch any nice HD pictures (real 1080 or 720) don't even consider it! I guess it works fine for SD users, but its not my case, and I felt really disappointed.
Pros: Easy To Set Up, Simple Controls, Sleek/Compact
