Help about video recording.

[cosecti]

The problem is this, I start to use Procast today but while and after recording from the game I can only hear the audio, video is a black screen in both cases, during the live streaming, and then in the On demand option. Any ideas about this? :S
Thanks

btw the game crashes(every time) a few seconds after start broadcasting but I guess that happens because I need more RAM, (actually that's another problem I have but I guess this time it's mine) You think so too?

:S
