I was involved in this SW release in a way. We had a severe ICMP crash in Sweden a while back with an Indian movie. It was a major release (encrypted w English subtitles) from a "real" lab. The film stopped after 20 minutes and the ICMP crashed (same thing happened in both screens at this site).
We sent logfiles and a drive containing the DCP to Belgium. Barco made a test run in Liege (I think) and the same thing happened there. Then this new SW version came out.
What they actually fixed I don´t know.
