You can now download the popular ABC TV show "Lost" from the Xbox Live Video Marketplace. Not only can you get the latest episodes as soon as they air, you can also pick up any episode from the previous three seasons, which is very useful for reviewing the prior clues! You can choose to download the show in either standard definition for 160 points ($2) or high def for 240 points ($3). According to saladhats, this actually makes a season of high def cheaper on Xbox Live than on Bluray by about $24! If you aren't watching "Lost," then you've missed out on one of the best shows on TV, so download the old episodes and get caught up already!
