Unexplained Internet Usage

Hi,

I have recently noticed some unexplained internet usage in the Gigs from my appleTV. During one week that i was sick with bronchitis, i did not use the internet at all, but the previous week i rented few movies with the appleTV. The week i wasnt using the internet, i noticed 3Gb for 4 days of internet usage.

Upon further follow-ups with my ISP (videotron), they told me roughly the hours of internet usage, and it was during the wee hours of the morning.

I set up a hub and a machine to run dumpcap, and I saw that the appleTV would be contacting akamai technologies and the protocol looked to be something related to media.

This Wednesday, i rented another movie at 8:30pm, I checked my internet usage the next day and it showed 3.8Gb for Wed, and another 3.7Gb on Thursday morning at 00:04 am.

Anyone know why appleTV would contact and continue downloading after renting a movie double the bandwidth of a movie ? I understand that while watching the movie, it is streaming it, but when you are done watching it, it should have finished downloading it to the appleTV.

Now, I have completly disable my internet usage for the appleTV until i got to the bottom of this. I blew my internet usage last month and I estimate that the appleTV donwloaded close to 15Gb of stuff.

THanks.

Looking at the appleTV disk usage, there is a 7.8Gb of stuff.
