The zip file (SPL2937_v0408 )from official site(JVCPro-MSIS (http://www.service.jvcpro.eu/public/document.cfm?prog=ProdSoft.cfm&Model=GY-HM600E)) IS CORRUPT. Seems like it was not uploaded complet, is very small (2.44 Kb). It is someone who used this firmware update file?

I have this downloaded and updated with no problems.
The content compared to 407. There are blocks, deleted, modified and added, menus are identical.

I was hoping to get 60p live streaming option that I got on my 850 newest firmware, still stuck at 30p.
