I jumped the gun in using sourceforge for issue tracking as we’ve run into a few issues. So we’ve decided (while relatively few bugs are filed) to migrate to Googlecode for tracking issues (bugs and features). They already host our source code and have better integration with their checkins.
The support docs on http://www.xuggle.com/xuggler/support have been changed to point to Googlecode and Robert is in process of migrating the feature and bug requests you have filed on source forge over to googlecode.
Please file new bugs, and add any comments to your existing bugs, in their new Googlecode issue locations.
Sorry for any inconvenience,
