Same Problem here. I'm living in germany and connected to a 3mbit DSL-Connection. Starting HD-rentals needs between a couple of hours and days. Wifi and cablebound connections the same.
That's not acceptable. Everything else just works fine (youtube, streaming of iTunes-media from another computer) and even as 3mbit is not actually "highspeed" a complete download of the rental should only need about an hour.
3Mbps is too slow to stream the HD rentals. I was paying for "up to 3Mbps" on DSL, but when I tested the speed using speedtest.net I would get something between 1.5 and 2.5 Mbps. Had the exact same problem: low quality YouTube and podcasts would stream just fine, but the HD video podcasts and the HD itunes rentals would take forever to buffer. Netflix still streams pretty quick because, unlike iTunes, Netflix samples your bandwidth and adjusts the video quality accordingly. iTunes rentals don't do this: they give a fixed HD video quality, and it takes however long it takes.
Based on the size of a typical HD tv show from iTunes (~1.5 GB for a 45 minute show), you'd need a sustained connection of over 4.4 Mbps in order to download the show faster than than the bit rate of just playing the show. And you will really want more than that to deal with hiccups in the bandwidth. I upgraded from an "up to 3Mbps" connection to a "up to 10 Mbps" connection last saturday, and it completely solved my streaming problems. Now the HD shows, movies, and podcasts all are ready to play in under 30 seconds. Also my Netflix streaming is now giving me HD quality whereas it wasn't before. Upgrading was only an extra $5/month. worth it.
And, from my experience, I can tell you that the time estimates for how long it will take before the rental is "ready to play" are not generally reliable. They probably ping the network to see what the instantaneous bandwidth is, and give an estimate based on that. But your bandwidth will vary depending on your own network traffic, and potentially how much other people are using the network in your region. So the "ready to play in. . ." estimate jumps all over the place. Also, it apparently does not continue downloading the show when the apple tv goes to sleep.
