I am trying to render a 10 minute clip with minimal effects added. Every time, Screenblast crashes (at a different time each time). The source video was captured by ScreenBlast from a Digital 8 camcorder via Firewire. The source video plays fine on Windows Media player.

Could this be a DirectX version issue? I have the same problem trying to render the source file with TMPGEnc although the error occurs at different times.
