Sorry for posting in a relatively old thread.
I ran into issues parsing the RSS feed with common PHP aggregators such as SimplePie or MagpieRSS. The forum XML is perfectly valid, but these libraries seem to cringe at the format of the feed URL (probably at the rss/{forum_id} descriptor).
For the record, what worked for me was to create a local proxy to read the XML under a simpler URL format (e.g. feedproxy.php?f=1839).
