I think I'm still a little frustrated with mine:
- The audio stutter is the most annoying. Either listening to commentary or music its very noticeable.
- I've had my TV randomly turn on at ~5am (I assume the box restarted for an Android update?, then woke the TV and Amp)
- Freezing video - the image freezes for ~15 seconds every so often, but the audio functions normally.
- When watching delayed/timeshift (for say 30mins+) it eventually just randomly jumps to a different time, or even reverts to live.
I don't think its a faulty unit and is software related. I'm not sure if its refundable within a year, but I must admit I haven't enjoyed it coming from a TiVo device. I don't use the OnDemand options much as I have another device for that, but would consider if I had IR added.
