I have an HR22-100 and the download took the normal amount of time. I haven't had a CE on this box since MRV went national. It did clear out the guide cache and I did get an "additional download" at the point where I would have gotten a tv picture for the first time. I did see the "screen saver" icon for a few mins before the additional download was done and then I got a normal tv picture. I had heard that the new guide was fast on an HR22 but WOW! The difference is night and day.
