I dont know know why rss2blog is not working for you. I had tried it with different hosts and it works fine with all of them.

Moreover it has the no of items to pull from rss feed. It will not pull all items and post them all at once. So if you make an rss feed with 30 items and setup no of items 1 to 1 it posts two items each day. I dont know why, it should post one item only. Any how it is better than posting all items at once.
