If I begin to download a "short" (say an old musical live performance etc) that's about 6-7 minutes long, I can usually start watching it within a few minutes using a 1.5 connection. This is not, however, how I use VOD. I usually put a few items in the download queue, and come back later or even a few days later and watch one or more of them. I treat VOD much like I treat a Series Link or a program I've set to record. I simply time-shift it without the expectation of a true "on-demand" experience. Works fine for me but of course it's personal preference.
