For those of you who don't know this already, there's a really nice webpage for Longhorn football highlights.  Not only does this guy have highlights from every game in the 2005 (and most of 2006) season, there are a ton of fan-created highlight videos.  

Plus, I think he hosts all the videos himself.  The website hasn't been updated in ages, but its still a great way to see old Longhorn highlight films which are otherwise hard to get.
