I'm using Vegas 14 Build 270 64 BIT, I have a 31 minute MXF file that I need to render to PRO RES 422 LT @ 1920 x 1080p 29.97. When I go to render it will render for 2 to 3 hours and then V14 just hangs. I've tried this several times with the same results. I am using a Lenovo W530 laptop i7 CPU @ 2.40GHz, 8gb RAM, Windows 7 OS 64. Any help would be appreciated.

Regards
