I got the DCT6412 right around Christmas and, while it has a few quirks (see below), mine is doing all right. Because of those quirks, I was excited to read about the Moxi box in this thread, but when I went to read about it in the Moxi thread, now I'm pretty scared.
* No DVI output.
* Can't use the 4:3 override to push SD analog and digital to 480i (which means the box stretches it to 1080i)
* Just about as many tuner/PQ/DVR problems as have been reported for the DCT6412
* Complaints about the program grid
* Most of these problems (but not all) are supposed to be fixed in the next firmware revision which has been promised since August but now seems to be 'no earlier than March 1st'
If Huntsville's Comcast goes to the Moxi box, are they going to support both? I'm pretty close to getting my DCT6412 to behave properly and I don't want to have to redo that. I'm more likely to boot Comcast and go satellite.
My currently problem with the DCT6412 is that it seems to have developed the "no tuner feed when you power on until you play a bit of DVR'ed show". This is just an annoyance now because I usually leave it on. Supposedly, removing power and restoring it "fixes" this, but at the cost of having to redownload the program guide and losing your scheduled recordings, but I'm going to try it tonight (around bedtime) and see if that works. It *may* be caused by my 480i 4:3 override setting. If that is true, it goes from annoyance to seriously broken (but the Moxi box would still be unacceptible to me if the above problems aren't fixed).
Support for external USB2.0 drives would be *real* nice, tho'. Even if DRM prevents them from being used if the drive was connected to a computer, it would still be nice to boost my record time, particularly for HD.
