How long to download TV program in iTunes?
The time to download a TV show from iTunes will depend on the speed of your internet connection. On a slower DSL connection an episode of Stargate SG-1 (484MB) took about two hours for me. It seemed like it was downloading faster than normal for our connection. If you want to estimate how long it will take, time how long it takes to download one megabyte of the show and then multiple that amount of time by how many megabytes are left to download. iTunes does give you an estimated time remaining, but if your download speed is fluctuating, then it won’t stay accurate.
