DeckLink SDI and Flash Media Live Encoder

Here is my setup:


MAC PRO 8 core 24g RAM latest OS

BM DeckLink SDI

BM ATEM 1 Broadcaster

BM HyperDeck Studio

Sony XDCam 1080i 60fps



Here is the deal, wanting to stream live switch multi cameras and archive H.264 Files to upload to Vimeo...


The problem right now is I cannot record the H.264 in Flash Live Media Encoder, the file is always corrupt. Never had a problem going FireWire direct from camera, but once we added the SDI capture card and ATEM 1 M/E we started having these issues... All drivers are current on the card and switcher and we are using FLME Ver 3.2.1


Any ideas or pointers that I might be overlooking?


Thanks

We use a Decklink Extreme card with FLME without any problems. We are using a PC though and not ATEM.
