After I did that, I had no problem.

Thanks for the responses, guys! I couldn’t pay for this kind of support.

It makes me think even more that the issue's lurking in my own code, rather than in FeedBurner, since I figure you guys would have fixed an overall issue big enough to affect all PHP XML parsers :)</p> Eric: Thanks for the fast response!

I’m going to be poking into it more as I have time, though at the moment I don’t even know enough to say for sure that FeedBurner’s the culprit–just that every FeedBurner-processed feed triggers my bug. Since no one else seems to know what the issue is right off the bat, my current thought is that it’s something I’ve fumbled. :)
