The Podcast downloads are being especially squirrely today, so I just wanted to post to say that I'm aware of it. After Mark gets back from tour next week it will be first on his list of things to fix, so just hang in there for a few more weeks.
In the meantime, the full download should run about 1:30. If you're having troubles, I'd suggest waiting until tomorrow, Tuesday seems to be the sort of "Magic" day to download.
