The DVR box is working out very well. The stuttering I saw initially is gone. I have a feeling it was due to the initial guide data load after I hooked it up. I linkblogged a few of the resources I found; the Wikipedia page for the 6412 guided me to some good remote hacks. A little education on the implementation of the two tuners are helping to make operations smooth. We watched Lost in HD on delay and it was very smooth. The only thing that was goofy was that when the DVR was done recording the show (which was pre-programmed), the box turned off. Our playback location was saved, so it was only a temporary inconvenience, but one that should probably be corrected. I’m still very pleased with the box at this point.
