I just purchased a WDTV Live Plus a month ago. I would like to see more streaming services added to the TV Live Plus media player. Adding Amazon on Demand would be a great start! Blockbuster and Cinemanow use the primitive method of d/l the movie first before you can watch it. I was unaware when I purchased the WDTV Live Plus that I would need addtional hardware (USB Flash drive or Ext. USB HDD). Had I known this, I wouldn’t have purchase the WDTV Live Plus. I just thought every service was using the streaming method.
Your post sounds more like a good Feature Request; best placed in the Ideas Exchange section. This way someone from WD will be sure to see it and will allow more users to support your idea. However, I would first search and make sure that there are no other active Feature Requests suggesting the same or similar improvements. If there is, then you could add your post and vote on it.
