480p is known as EDTV, it is not HDTV. The CPU in the xbox certainly is incapable of doing a software decode of HDTV, especially 1080i. The nvidia graphics chip in the xbox could do xvmc, but my attempts (not on an xbox) do do hardware decoded 1080i on such a CPU did not succeed, so I doubt the xbox could do it but I have not tried an xbox itself. Myth's xvmc support still has some issues as far as being able to seek, with various other ones reported. So my guess would be, unless somebody pipes up, that the answer is no, you won't get HDTV from an xbox, though you could get fine EDTV. The xbox is cheap and quiet but high end hardware is now costing not a lot more than it, though it's not as quiet because it needs bigger fans. Right now if you want HDTV your curse is you need a big enough CPU to need a fan you can probably hear, though there are lots of people who sell fans and cases that are pretty quiet. Even if the fan is quiet when the CPU is idle, decoding will use most of your CPU and crank up the heat. So does commercial elimination or transcode. I find it amusing that, if I pass by the TV room just _after_ a show I have recorded is on, the machine gets loud for a while. I need to move commercial skip to a different backend.
