my experiences with blackmagic (as event-technician) are not that great, i'd cry "hooray".. their sdi-hdmi-converter freeze or auto-converts with wrong specs under some circumstances, their sdi/hdmi-audio-de-embedder as well. the only positive thing i can say, they show good ideas - but if its not good coded since the beginning, you'll never get a final good firmware, this happened a lot in the past. so i stopped looking at bm-tech. their "new ideas " are boring me.
