Might have solved the problems with CP "RSS feed" (different character encodings of your page and the incoming feed). Now you are able to select the source content-type of the incoming feed. http://code.google.com/p/phpwcms/issues/detail?id=155
I think you can delete the --> field cref_module_2 in the --> TABLE `phpwcms_crossreference`.
DON'T mix it up with the field cref_module !!!
Anyway they all are empty, aren't they?
