What you get depends on location. Try posting in the local reception forum in your local Comcast thread.
That said, when I had my install the first box the guy brought in didn't have DVI out. He had to go back out to his truck and get an identical model that had the output.
I don't know why anyone would have issues going from DVI to HDMI. It's just a simple adaptor cable. Do note, however, that there have been issues with Comcast implementing HDCP on the Moto boxes. Right now it's not that big of an issue, it simply requires that you flip the channel up and then down if you've switched to some other source while the STB was on.
Finally, if you're getting a DLP set, I'd use DVI/HDMI.
