It is extremely slow when changing channels, even from the guide. It can take up to 5-6 seconds for the command to occur. It has actually gotten worse in the last few months. Just too irratating to deal with. I have the protection plan by the way, and tried to get a new DVR that way, but they just sent me a refurbished HR20-700, which I sent right back. Since they can't guaranty what I will get, I gave that up after trying that as well and will just contact a local retailer.
