My wife and I were interested in watching one of two movies tonight - "Chronicle" or "Haywire" - but neither was available at any of our local Zip kiosks. So I thought I'd try renting "Chronicle" from iTunes. The rental-and-download process was simple, and I had the movie on my home-office PC in ~30 minutes. (Our current ISP is Primus @ ~3-4Mbps; we'll be switching to TekSavvy @ 12Mpbs later this month.)
I wanted to put the movie on my wife's laptop, hook it up to the receiver and watch the movie on the big screen but, as it turns out, the rented movie won't play on any other device because of DRM, and I didn't have anything installed on my PC with which to crack it (and I didn't feel like getting into searching for free software to download and install in order to crack the DRM).
So we decided to pull a couple of Poangs up to the 21.5" monitor that I use for my PC (PC to monitor is VGA; PC to stereo receiver is analogue stereo) and watch the movie in the home-office. We started the movie and quickly noticed that the audio was not in sync with the video. (This has never been an issue with any video - streamed or off my HDD - I've watched on my PC.) I did a bit of cursory Googling and fiddled with a few settings, but nothing seemed to work. So, every few minutes I would pause the movie for a second, which would allow the audio and video to get into sync...for a few minutes.
This was a disappointing introduction to renting movies off the Web. Thankfully, although the movie was OK, it wasn't so good as to regret having watched it the way we did.
