In sports is there a way to get an entire previous season worth of games anywhere, online or in dvd form?

I've missed a couple seasons of football through work and other reasons. I'm just wondering if there is anyplace out there, for example, I could get the 2007-2008 season of the Green Bay Packers or the Saints? I've seen season highlight videos a plenty but not complete games anywhere. I was also looking to become a fan of NRL rugby and would love seasons worth of games for that as well.
