Don't forget to watch Lost on Wed night when they rebroadcast an 'enhanced' version of last season's finale. I'm guessing it will be a cross between Lost and
pop-up video.
Also, if you didn't know, there are a series of 2 minute 'missing pieces' of scenes that provide extra information.
You can watch those (13 of them I think) at abc.com
http://abc.go.com/primetime/lost/missingpieces/indexor you can download the flv from lostpedia
http://lostpedia.com/wiki/The_Watch (just navigate to each episode and the download link is at the bottom of the page. each file is about 9mb and you need a flv player to watch.)
