The only HD videos from Halo 2 that you're going to get are from H2V's campaign and you can easily find them on youtube (Believe shock120 has all them in his channel).
The Original Xbox couldn't play HD (plus didn't have the connections for it) and during that time HD wasn't that important so they wouldn't make a HD trailer.
