Taly, the total size of the file has nothing to do with the issues I'm describing.
It really does, since it's completely related to bandwidth usage. Total size of the file divided by the length of play = bandwidth usage.
For instance, 3 GB / 2 hours = 1.5 GB/hour = about 3.3 to 3.4 Megabits/second. That's the network bandwidth you need to stream a video file that is 3GB in size and 2 hours in length. (And that's assuming you get 100% efficiency and no slowdowns.) Blu-Ray quality 1080p video is unstreamable short of a 40 Megabit/second FiOS connection, and even then you aren't going to get anywhere close to it since you'll run into internet bandwidth bottlenecks.
Both of those are well within the 108 Mb/s limit of wireless G LAN, though. You're more likely to run into other problems that cause slowdowns than the fact that you're running wireless. Remember, home wireless LAN bandwidth is always far faster than cable or satellite streaming bandwidth.
Bandwidth is the only pure measure that is unaffected by such things as the compression of the file being watched, since the method of transmission isn't really doing any additional compression of the file. The size of the file over the speed at which it needs to be streamed is a pure, hard measurement. If the file is compressed, that just means there is additional work to be done at the end decompressing it for viewing, but the transmission method doesn't care about that--a 3GB, 2 hour video file needs to transfer at 3.4 Mb/s in order to stream without stopping to buffer. That's all there is to it.
