Sounds like some or all of the records lack a leader element, and that would lead to the "yaz_marc_read_xml failed" you've been seeing. Making sure that each record starts with a leader element along the lines of <leader>00000 a2200000 4500</leader> might get yaz-marcdump to emit ISO2709 records. However, for those to be useful, you'll likely want to set positions 5, 6, and 7 in the leader to values that make sense for the type of records you're dealing with.
