With the Xbox 360 Live Marketplace, you have 7 days from the time of purchase to start the movie, and once you start to watch the movie, you then have 24 hours to watch it. This is important for HD movies, as with my experience I had to leave my 360 running overnight to download a movie, and then found myself too busy the following day to watch it, so I made sure not to start watching it until I was ready to sit down for the whole movie.

Within the 24 hour viewing period, you can watch it as many times as you want.

Personally, I would hope that Apple gives people a full week-long rental period, or at least 3 days so that all family members have a chance to watch a rental. It would be imprtant for allowing parents to pre-view a movie before deciding whether kids can watch it as well.
 
I believe that MS will eventually integrate the Windows Media Player on Vista, Zune, music store and Xbox Live along with some integration on the Windows Mobile platform so that the same music, video and simple arcade games can be used across many devices with one subscription. I believe they have stated this will be the strategy. They would be silly not too.

They are certainly taking their sweet time though. I think the groups in Redmond are not even the same teams (although I may be mistaken)

Full integration could at least present viable option to Apple's Ecosystem, as Apple all but ignores gaming. They are making money on Xbox finally and Live has been a money maker since the launch of the 360. Actually I'd be willing to bet that everything above makes some profit for them, except music and the Zune at this point.

Their execution certainly seems to be worse that it should be though doesn't it?
