I installed 1.2a, and all seemed well until I tried to schedule some recordings. They didn't show up on the list, so I tried emptying the channel database. All went as expected until the channel-scan wizard showed up--with no check boxes at all! So clicking "next" simply caused it to close. I fiddled around a bit with no success, then tried reinstalling. I got exactly the same behavior. I have an HVR 1600 74021 and WIN XP.
