Kaoru, thanks for posting this! They must have changed it, because the BroadwayHD offer is now only for one week, although the Berkeley Rep production will still be available for 2 weeks.
Thanks also for reminding me about BroadwayHD. They've got some good stuff there. One of my goals is to see every Tony-winning play and musical. I've got 12 musicals and 25 plays to go. One play I thought I would never see is Nicholas Nickleby, because I think it's unlikely ever to be revived. I didn't realize the original production had been filmed (and now available at BroadwayHD). It's not the same as live theater, but close enough I can experience a version of it and cross it off my list.
On the play side, there are a lot of plays from the 50s and 60s that may never be put on again, but I think the musicals are possible. I just need Encores to put Kismet on again (and Redhead, while they are at it).
