Actually they are not just sitting on Cinemanow. They continue to run it, and they have not yet put their logo on it. I have heard that they are working on something, (don't know exactly what) but a look at their website shows a bit of what Reeltime should be doing.
Like sell through, or "Burn to DVD." and also selling DVDs, ordered on the website, delivered by mail. It all adds up, and the customers for a movie rental are the same customers for a movie purchase. Many rentals become purchases, so the company needs to offer that. It is called getting the most out of your opportunities.
