A question about potplayer

Hello everyone,
I'm new these forums. Great to see all the resources you've made available.
I've been searching for an answer question I've bee having and was wondering if any one of you would be able to help me out? It would be greatly appreciated as this problem has been plaguing me for a while now.

Does any one know how I can capture 1280x720 video using potplayer without recording the reduced screen? Because I have not been able to figure it out myself.

My capture card is a timeleak HD80E. Do you think this has anything to do with it?

Thanks very much for your time.
Any help you can offer would be appreciated.
