I’m sure it would take longer to dl than to run one yourself, but I’ve got a hinted h264 mp4 that’s over 2g.
All of my really big files come from ripping DVDs with HandBrake. The big problem right now is that, at least on my machine, qt-quickstart tells me the file is too big and MP4Box gives me an “out-of-memory” error, so I couldn’t find an easy way to hint them (supposedly forthcoming in HandBrake). Since I wanted to test it, I made a hinted file with QuickTime Pro.
If you’d like it to test with, let me know. I’d prefer not to post the url and have my little server burst into flames 🙂
