Hi Tom, and all, I've had a look at *PDU to Tagged Stream* block. Regarding to adding tags, both this block and *Burst Tagger *contains add_item_tag() function. Which block inserts the main stream tags? I don't quite under stand what *Burst Tagger* does since it contains both add_item_tag() and get_tags_in_range() function.
